#Gaussian software reference software
These elements have been incorporated into a software package called deMon that is being tested and applied over a wide range of systems and interaction types (organic and inorganic molecules, transition-metal complexes, clusters, and surface models, van der Waals interactions, hydrogen bonds). of the Rights in Technical Data and Computer Software clause at DFARS 252.227-7013. These improvements include: the use of (relativistic) model core potentials, basis set preparation, more efficient integral evaluation (following Obara and Saika), the calculation of energy derivatives, automatic geometry optimization, calculation of vibrational frequencies, a “hybrid” method for simultaneous geometry and electronic structure optimization that incorporates elements of the Car-Parrinello approach along with conventional potential energy surface walkers, and the use of non-local functionals involving the gradient of the density. software gaussian casscf multi-reference. Gaussian 09 IOps Reference Second Edition Edited by Marco Caricato Æleen Frisch Joanne Hiscocks Michael J. The only exceptions occur with long established methods such as. These references are given in the discussions of the relevant keywords. Gaussian keywords The following is are some Gaussian keywords that can be used in the route section of the Gaussian input file. In general, we recommend citing the original references describing the theoretical methods used when reporting results obtained from Gaussian calculations, as well as giving the citation for the program itself.
We review some of the progress made by the Université de Montréal group over the last few years, and especially over recent months, towards developing, testing, and applying Gaussianbased density functional techniques of increased accuracy, speed and functionality. applicability for each built-in basis set in Gaussian: Basis Set Applies to Polarization Functions STO-3G H-Xe 3-21G H-Xe or 6-31G H-Kr (3df,3pd) 6-311G H-Kr (3df,3pd) 4.
