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.
