Properties of nitromethane anion: Low electron binding energy: AEA = (172±6) meV = 1387 cm -1. vibrational autodetachment possible by excitation of vibrational modes with ħ ≥ AEA. Adams et al., J. Chem. Phys. 130 (2009) So far: vibrational spectrum of CH 3 NO 2 - well characterized in CH stretching region, but not in region around AEA. Weber et al., JCP 115 (2001) 10718; Schneider et al.,JPCA 112 (2008) 7498; Adams et al., JCP 130 (2009) ; Schneider et al., JPCA 114 (2010) 4017 Low-energy modes crucial for IVR in the molecule, needed for full characterization of ion. ^ Motivation
