Gaussian is designed to model a broad range of molecular systems under a variety of conditions, performing its computations starting from the basic laws of quantum mechanics. It provides a wide number of ab initio models, some semiempirical models, and Density Functional Theory (DFT) methods. Gaussian can predict energies, molecular structures, vibrational frequencies and numerous molecular properties for systems in the gas phase and in solution, and it can model both their ground state and excited states.
