The 1982 Chemistry ArtfclesMost Cited, 1982-1984

., .- l--- I-A *.-. ----- ---

Thh is the third annual Current Con-tent@’ (CC@ ) study on most-cited chem-istry papers. To date we have examinedarticles from 1980 and 1981 that werecited over a three-year period. 12 Thisanalysis dkcusses the 1982 chemistry pa-pers from the Chemistry Citation Irs-dexTM (CC~), a subset of the ScienceCitation Index@ (SCi@ ). These paperswere most cited from 1982 to 1984.

The CC1 is a new M@ database that isnot yet available in print or online. Amore complete description of it can befound in CC essays from June 25, 1984,3and March 25, 1985.2 Earlier this yearwe used it, along with Current A bstmctsof Chemistry and Index Chemicufl(CAC&I@ ), to help identify the most-cited 1981 “chemist& papers.z In thattw~part study we fwst used the sourcejournals covered by CAC&IC to identify103 articles, primarily in pure and syn-thetic chemist~. A second Sit of 100 pa-pers, based on the CC1, fiIled in thoseother areas of chemistry covering physi-cal, inorganic, organic, spectroscopic,and analytical chemistry,

For the present analysis we used theCCZ to identify 105 1982 papers. (SeeBibliography. j During this process weeliminated any papers from biochemis-try or other fields ah’eady covered by ourannual studies of the Iiie and physicalsciences. The borderlines between fieldsare not always easify identified. Modemchemistry touches many subdisciplineintertwined with biochemistry or phys-ics. However, each iteration of this se-lection process identifies significant pa-pers from a wide variety of areas.

Journals

The 39 journals that published the 105papers are listed in Table 1. They en-compass many different areas of chemis-try and confirm, in part, that the list inthe Bibliography is quite varied. TheJournal of the American Chemica[ Soci-ety (1A CS), which dominated the firstfist of 1981 papers, published the largestnumber of papers in thk study—21. Butthis is less than one-thwd of the 74 JACSpapers in that 1981 group. It is also lessthan the number of JACS papers (35)publiihed in the 1980 study.

Analytical Chemistry has the secondgreatest number of articles in the Bibli-ography (nine), foffowed byA ccounts ofChemical Research (six), the Journal ofChemical Physics (six), and the Journalof Physical Chemistry (six). These fivejournafs account for almost 50 percentof the papers in the Bibliography. Wewill discuss the latter two in an upcomingessay on physical chemistry/chemicalphysics journafa. But the .fourna[ ofPhysical Chemistry, which has six papersin thk listing, had only three in both listsin the 1981 study and none at all in the1980 analysis. Science, which publishedseven papers in 1981, has just three pa-pers here.

One new journaf appears in Table 1.Organometdics, established in 1982 bythe American Chemical Society, coversthe synthesis of organometallic com-pounds, their structure and bonding,chemical reactivity and reaction mecha-nisms, and applications. The journal de-fines an organometallic compound as

497

one “in which there is a bonding interac-tion (ionic or covalent, localized or delo-calized) between one or more carbonatoms of an organic group or moleculeanda main group, transition lanthanide,or actinide metal atom (or atoms).”4 Or-ganometallics published one paper inthk study authored by David L. Thorn,Central Research and Development De-partment, Dupont Company, Wilming-ton, Delaware.

Heterocycfes, an international reviewjournal published in English by the Sen-dai Institute of Heterocyclic Chemistry,Sendai, Japan, is also represented for thefirst time in one of these most-cited lists.Yoshinori Yamamoto and KazuhiroMaruyama, Department of Chemistry,Kyoto University, Japan, discuss “Or-ganometallic compounds for stereoregu-lated synthesis of acyclic systems. Theirapplication to the synthesis of the Pre-log-Djerassi lactonic acid. ”

The Prelog-Djerassi lactone has fre-quently been discussed in papers that ap-pear in our lists of highly cited articles.As it happens, Vladlmir Prelog, Labora-tory of Organic Chemistry, Swiss Feder-al Institute of Technology, Zurich,Switzerland, coauthored a new method-ological paper in this study with firstauthor Dieter Seebach, also of the SwissFederal Institute of Technology. Enti-tled “The unambiguous specification ofthe steric course of asymmetric synthe-ses,” the paper was published in A nge-wandte Chemie—International Editionin Engfish. Since this journal is pub-lished in both German- and English-lan-guage edhions, we un~led any citationsto papers published in both versions.The Seebach-Prelog paper has received57 citations since 1982, including 19 in1985 alone. According to the authors,“The nomenclature of organic chemistryhas not kept pace with the staggering ad-vances made in asymmetric synthesisover the last 15 years. Efforts to specifythe steric course of stereoselective reac-tions by use of the terms erythro andthreo and by other descriptors have ledto ambiguous notation and consequentlyto [utter] confusion. We prqpose.. .amethod . . .for the unambiguous specifi-

cation of the steric course and the prod-uct configuration of diastereoselectivereactions.”s

Nobelfsts

Prelog is one of three Nobel authors inthk study. He was awarded the prize in1975 with John W. Cornforth (Australiaand UK) for their work on stereochemis-try, specifically for investigating thestructure of biological molecules such asantibiotics and cholesterol. Sir GeorgePorter (UK), who authored a paper inthe Bibliography with James R. DarWentand colleagues, Davy Faraday ResearchLaboratory, The Royal Institute, Lon-don, shared the 1967 prize with ManfredEigen, (Federal Republic of Germany[FRG]), and Ronald G.W. Norrish (UK)for investigating high-speed chemical re-actions. The third Nobelist is RoaldHoffmann (US), whose work has ap-peared often in these lists. He washonored by the Nobel committee in 1981with Kenichi Fukui (Japan). Hoffmann isrepresented in the Bibliography by twopapers, one of which is his Nobel acceptance lecture, “Building bridges betweeninorganic and organic chemistry. ” Hoff-mann dedicated th~ lecture to hisformer teacher, Robert B. Woodward,Harvard University, Cambridge, Massa-chusetts, whom he considered “a su-preme patterner of chaos.”b Woodwardwon the Nobel Prize for chemistry in1965.

Geograpbfcal and InstftutfodAfffffdoris

I mentioned earlier that Japan pub-lished one journal in this study (Hetero-cycles). The paper in the Bibliographyfrom that journal was written by Japa-nese researchers. “Only” two additionalpapers in the Bibliography are from Jap-anese institutions. In contrast, Japanwas represented by 11 articles in the1981 study. Alf of those papers appearedin Part 1 of that analysis where JAG’Sdominated the liit. Seventy papers inthis study have US institutional address-es, while papers from Canadian institu-

(The 1982impact factor equafa the number of 1982 citationsreceived by the 1980-1981 articles in a journal,divided by the number of articles published by thejournal during the same peried.) Data were takenfrom the 1982 .KW. The figures at the right in-dicate the number of papers from each journalthat appear in the Bibliography.

tions rank second with 10 papers. Thesefigures have not changed much from thetwo previous studies. Eight papers withUK affiliations appear in the Bibliogra-phy, followed by seven articles with au-thors from institutions in the FRG, sixfrom Switzerland, five from France,three each from Australia and Japan,

two from Belgium and two from Den-mark, and one each from institutions inThe Netherlands, Israel, and Italy.

These geographic rankings are listedin Table 2. There are many multination-al institutional collaborations among the105 papers whose national affiliationsare summarized there. Six US articleswere cowritten with authors from insti-tutions in Australia, Belgium, Canada,FRG, Switzerland, and the UK. Canadi-an institutions appear on seven paperswith authors who worked in Denmark,Italy, The Netherlands, the UK, and theUS. In 1981 authors in the US and inCanada coauthored papers with five andtwo other nations, respectively.

Thirteen nations are represented inthk study, but only two papers werewritten in a language other than English.The paper by Andreas Pfaltz and col-leagues, Swiss Federal Institute of Tech-nology, Zurich, and Marburg Universi-ty, FRG, in Helvetica Chimica Acts, waspublished in German and concerns thestructure of the porphhoid ligand sys-tem. Claude Couret’s short French arti-cle appeared in Tetmhedron Letters.

previous studies is another interestingaspect of this analysis. North DakotaState University, Fargo, is representedfor the first time in our chemistrystudies, with three papers (P. Boudjouk,M.M. Francl, M.S. Gordon). TheGuelph-Waterloo Centre for GraduateWork in Chemistry (GWC)Z, a collabo-rative and innovative program of boththe University of Guelph and the Uni-versity of Waterloo, Canada, contribu-ted six articles (P. Beak, A.J. Carty, C.Douketis, C.A. Fyfe, J. Klinowski, J.M.Thomas). This center is only 10 years oldbut is claimed to be “one of the largestand best chemistry graduate programs inCanada.”T Giacinto Stoles, who is a co-author on the paper by ConstantineDouketis, was the acting director of thecenter in the year of its foundation. Ar-thur J. Carty was the center’s first direc-tor from 1975 to 1979. Its current direc-tor is R.J. Balahura. Griffith University,Nathan, Australia, is also a relativenewcomer to these lists. (See paper byD.T. Pegg and colleagues.)

These 10 papers range in citationsfrom 35 to 77, while the most-cited pa-per in the study was cited 82 times andthe least-cited, 35. The average citationrate for alf 105 papers was 46-4 in 1982,18 in 1983, and 24 in 1984. These figuresshould remind the reader that new andless familiar institutions also make im-portant contributions to science. Tradi-tional research giants such as MIT andthe University of California, with itsmany campuses, usually predominate insuch studies. The latter two institutionscontributed 10 and 9 papers, respective-ly. All but three of MITs papers arefrom its Department of Chemistry. TheUniversity of California research wasconducted at five dtiferent departmentsor laboratories on six clifferent cam-puses. Table 3 contains the ranked list ofall 90 institutional affihations represent-ed in the study. (GWC)2, mentionedabove, appears on six papers. AlliedCorporation in New Jersey is represent-ed by four papers, as is Rice University,Houston, Texas; University of ToulouseIII (Paul Sabatier University), France;

University of Texas, Austin; and theUniversity of Cambridge, UK.

Most-Cited Paps and Research Fronts

Researchers at an institution inDuarte, Caliiomia, authored the most-cited paper in the Bibliography. Hirata-ka Ito, Asahi Chemical Industrial Com-pany, Ltd., Shmuoka, Japan, worked inthe Molecular Genetics Department atthe City of Hope Research Institute,Duarte, for two years with colleaguesYoshimasa Ike, Satoshi Ikuta, andKeiichi Itakura. Itakura is stifl at the Cityof Hope Research Institute, while Ikutais now at the University of Caliiomia,San Diego. Ito and Ike have since re-turned to Japan. These four authorswrote the methodological paper in theBibliography entitled “Solid phase syn-thesis of polynucleotides. VI. Furtherstudies on polystyrene copolymers forthe solid support,” which was publishedin IVuc[eic A cids Research. It is the sixthinstallment in a continuing series. Theeighth and most recent part appeared in1983 in Nucleic Acids Research.8 Al-though the title of the 1982 article andthe journal that published it are life sci-ence in nature, the article’s referencesinclude several to Tetrahedron Lettersand JACS. According to the authors, “Asimple solid phase method for the syn-thesis of oligodeoxyribonucleotides hasbeen developed using the phosphotries-ter approach. Mononucleotide couplingunits are sequentially added to the poly-styrene copolymer with 1YO divinylben-zene and two kinds of oligonucle~tides.. are synthesized in a relativelyhigh yield.”g In 1982, the year that thepaper was published, 14 researchers cit-ed it. In 1983 the paper received 31 cita-tions and in 1984,37. So far in 1985 it hasbeen cited 19 times.

Two research fronts include Ito’spaper as a core document. It is one of 31core papers in “Methods of biosynthesisof DNA and cDNA cloning into Eschen”-chia co[i in the production of human in-sulin” (#83-0684). These 31 core paperswere cited by 4251983 papers. Two ad-

cal modef” was written by two physicistsand three chemists. According toStoles, the authors of this paper had to

aPPeal to the advisory board of the Jour-nal of Chemical Physics in order to getthe article published. 11

ISI research-front information is sum-marized in Table 4, where we list the 21research fronts that include at least twopapers from the Bibliography as coredocuments. In this study, a total of 86fronts are represented by 81 papers. Sev-eral fronts dwcuss fast-atom bombard-ment, nuclear magnetic resonance spec-troscopy, mass spectrometry, photo-chemistry, and liquid chromatography.Front #83-M72, “Techniques and appli-cations of fast-atom bombardment in re-sorption and secondary ion mass spec-trometry, ” includes six papers from theBibliography. This is about 16 percent ofthe 38 papers that are core to it.

Five of the 105 most-cited chemistrypapers in the Bibliography are core to“MNDO and other ab initio molecular-orbital calculations of electronic struc-ture, vibrational force fiefds, and otherproperties of molecules” (#84-2764).One of these papers is the second most-cited article in this study. Having re-ceived 77 citations from 1982 to 1984,this JACS paper by Mark S. Gordon, J.Stephen Binkley, John A. Pople, Wil-liam J. Pietro, and Warren J. Hehre, De-partments of Chemistry, North DakotaState University, Fargo; Carnegie-Mel-lon University, I%tsburgh, Pennsylva-nia; and the University of California, Ir-vine, discusses “Self-consistent molecu-lar-orbital methods. 22. Small split-val-ence basis sets for second-row ele-ments.” It is also core to “A b initio mo-lecular-orbital studies includlng correla-tion of electronic structure and protontransfer in hydrides, cation radicals, andother species” (#83-2634).

Gordon and colleagues also appear ona paper by fwst author M]chelle M.Francl, Department of Chemistry, Uni-versity of California, Irvine. This articleis Part 23 in the same series on self-con-sistent molecular-orbital methods. Itwas published in the Journa[ of Chemica[

Physics and is also core to research front#84-2764 discussed earlier. The most re-cent article in this series was published in1984.12 And Part2113 was the most-cited

paper in the 1980 chemistry study. Thkarea of chemistry has become a majortopic of research in the past few years.This will be even more apparent in ourupcoming study of physical chemis-try/chemical physics journals.

Incidentally, many papers in thisstudy are multipart series or follow-upsto older papers. For example, the paperby Donald L, Baulch, Department ofChemistry, University of Leeds, UK,and colleagues “updates and extends aprevious critical evaluation of the kinet-ics and photochemistry of gas phasechemical reactions of neutral species in-volved in middle atmosphere chemistry(10-55 km altitude).”ld The original arti-cle was published in the Journal of Physi-cal and Chemical Reference Data in1980.1S

A two-part paper in this study is inter-esting because each part appears sepa-rately in the Bibliography, but each hasbeen cited about the same number oftimes. In addition, each paper was writ-ten by a completely different group ofauthors. “Laser microprobe mass spec-trometry. 1: Basic principles and perfor-mance characteristics” by Eric Denoyer,Ren6 Van Grieken, Fred Adams, andDavid F.S. Natusch, Department ofChemistry, University of Antwerp, Wil-rijk, Belgium, appeared in the January1982 issue of Analytical Chemistry andhas been cited 47 times. Part 2 of the ar-ticle, “Applications to structural analy-sis, ” was published in the same journalthe following month. It was written byDavid M. Hercules, Robert J. Day,Kesagapillai Balasanmugam, Tuan A.Dang, and Chung Ping Ll, Departmentof Chemistry, University of Pittsburgh,Pennsylvania, and received 45 citations.As a “set,” the two papers have been co-cited 23 times.

Most multipart papers are authoredby the same or at least some of the sameresearchers. The Denoyer and Herculespapers, however, were written by two

separate research groups because of a“coincidence.” That is, the editors ofAnalytical Chemistry asked Hercules towrite a paper on laser microprobe massspectrometry, but at about the sametime they received a manuscript in thisarea from Denoyer. That paper mainlydkcussed the instrumentation of massspectrometry, while the Hercules paperfocused on the application of the tech-nique to organic molecules. The editorsthen asked both groups of researchers ifthey would be willing to publish their pa-pers together as a two-part study. 16 Asyou can see, they agreed.

In these studies it is not uncommonfor an author to appear on more thanone paper. Six researchers on the 105 pa-pers (A.J. Bard, C.A. Fyfe, J. Kliiowski,S. Masamune, S. Ramdas, J.M. Thom-as) coauthored three papers each, whale16 were on two papers. They are toonumerous to list here. Two hundred sev-enty-one different researchers appear inthe Bibliography. Almost 20 percent ofthese wrote their papers alone or with

just one coauthor. The paper/authorbreakdown for all 105 articles is as fol-lows: 2 papers have eight authors, 2 haveseven; 1 has six; 15, five; 11, four; 22,three; 26, two; and 26 papers have justone author.

A two-author paper is one of two arti-cles cited 75 times, the third highestnumber of citations received by papersin this study. Donald F. McMillen andDavid M. Golden, Department ofChemical Kinetics, SRI International,Menlo Park, California, authored the re-view “Hydrocarbon bond dissociationenergies. “ “This review considers thebest available values for homolytic bonddissociation energies (BDEs) of variousclasses of neutral compounds . . . . Ourmajor emphasis is on hydrocarbons andtheir nitrogen, oxygen, suffur, halogen,and silicon-containhg derivations butwe include limited data for inorganicmolecules.”17 Not surprisingly, the An-nua[ Revie w of Physical Chemistry pub-lished this article, which is core to re-search front #83-3889, “Kinetics and

504

mechanism of laser-induced methyneradicals with alkanes and azoafkanes. ”

“Attached proton test for carbon-13NMR,” the paper by Stephen L. Patt,Varian Instrument Group, FlorhamPark, New Jersey, and James N. Shool-ery, Varian Instrument Group, PaloAlto, California, was also cited 75 timessince 1982.

This concludes our analysis of themost-cited 1982 chemistry papers andcompletes our series on the most-citedpapers from 1982. Recently we pub-lished the fiist two essays in the 1983series on most-cited papers. These cov-ered articles from the Me and physicalsciences. la, 19 As soon as we close out the1985 SCZ, we will identify the 1983 chem-istry papers most cited from 1983 to1985.

It is worth reiterating that we use threeyears of data for chemistry studies ratherthan two because experience has shownus that most well-cited papers in chemis-try and the geosciences require thatmuch, if not more, time before their im-

pact is felt. For example, the top four pa-pers from the 1981 study (W. Clegg,zoP.E. Garrou,zl M. Gfatzel,zz and D.W.Noid23) were each cited 96 (Clegg) or 65times (Garrou, Gratzel, Noid) from 1981to 1983. These counts have been almostequaled or surpassed in the two yearssince 1983. In 1984 Clegg’s paper wascited 59 times, and in 1985 itreceived 29citations. For the Garrou article thesenumbers are 44 and 35; for Gfatzel, 59and 36; and for the paper by Noid, 49and 37. In Figure 1 we have illustratedthese five-year citation counts. The peakyear so far for all but Clegg’s paper is1984, the third year after each paper’spublication. Next year it will be in-teresting to see the five-year citationcounts for the most-cited papers in thkstudy.
