Brand: Basis
In chemistry, Basis 2200 is a trade name for a widely used computational chemistry software developed by Gaussian, Inc. The program allows for the prediction and simulation of chemical behavior, including molecular structure, energetics, dynamics, and spectroscopy, using density functional theory or other theories at the quantum mechanical level of theory. The software has been used in various fields of chemistry, physics, and materials science for academic, industrial, and commercial research purposes. The name "Basis 2200" comes from the high number of contracted Gaussian-type orbitals that can be used in the calculations.
