Gaussian 09 Rev D 01 Em64t 43: A Powerful Computational Chemistry Software for EM64T Systems
Gaussian 09 is a popular software package for performing electronic structure calculations and molecular modeling. It can handle a wide range of chemical systems, from small molecules to macromolecules, with various levels of theory and methods. Gaussian 09 can also perform various types of spectroscopic and thermodynamic analyses, as well as reaction path and potential energy surface studies.
Gaussian 09 Rev D 01 is the latest revision of Gaussian 09, released on April 29, 2013. It includes several new features, bug fixes, and performance improvements. Some of the notable additions are:
A new keyword Opt=IRCMax to optimize the maximum point along an intrinsic reaction coordinate (IRC).
A new keyword Opt=IRCRecalcFC to recalculate the force constants along an IRC.
A new keyword Opt=IRCStepSize to specify the step size along an IRC.
