Gaussian is used to study molecules and reactions of definite or potential interest, including both stable species and compounds which are difficult or impossible to observe experimentally: short-lived intermediates, transition structures, etc. It can predict energies, molecular structures, vibrational frequencies-along with the numerous molecular properties that are derived from these three basic computation types-for systems in the gas phase and in solution, and it can model them in both their ground state and excited states.
Gaussian '16 is available for batch submission on Lop.
Use the utility "submit-g16" to easily submit Gaussian jobs to the queue.
GaussView is also available via Lop. To use it, connect to Triton using display forwarding, and type:

GAMESS is a program for ab initio quantum chemistry that can compute wave functions ranging from RHF, ROHF, UHF, GVB, and MCSCF, with CI and MP2 energy corrections available for some of these. Analytic gradients are available for these SCF functions, for automatic geometry optimization, transition state searches, or reaction path following. Computation of the energy hessian permits prediction of vibrational frequencies. A variety of molecular properties, ranging from simple dipole moments to frequency dependent hyperpolarizabilities may be computed.
Jaguar is an ab initio quantum mechanics package for both gas and solution phase simulations.
Jaguar is a module of the Schrödinger computational platform, which is available to the University's research community as part of SCS's Scientific Software Program. Please see the Program's page for pricing and access instructions.
This program is a molecular modeling package that specializes in electronic structure calculations, including ab initio, density functional theory, semi-empirical, molecular mechanics, similarity analysis, conformational analysis, and property calculations including QSAR.
