WebThe Gaussian Interface Introduction. The Gaussian interface permits the use of Gaussian 09 for the generation of energies and gradients. Most functions follow the generic quantum interface; only Gaussian-specific details are given here. In order to use the interface, the … WebMost internal options—IOps—in this manual correspond to normal Gaussian 09 keywords and their options, and it is highly suggested that keywords be used whenever possible. The standard method of using keywords includes a procedure for catching potential conficts between options before the calculation is run,
