Gaussian & GaussView

• Gaussian is a general purpose electronic structure package for use in computational chemistry. Current version 03 E01.

• Most widely used computational chemistry package. The latest release is version 2009.

• GaussView is a graphical user interface (GUI) designed to be used with Gaussian to make calculation preparation and output analysis easier, quicker and more efficient.
