Columbus Programs are a computational chemistry software suite designed for performing high-level ab initio electronic structure calculations of molecules and atoms. Developed originally at The Ohio State University, Columbus has become one of the leading software packages for studying complex electronic structures, particularly systems involving excited states, open-shell species, and nonadiabatic processes.

ab initio method
PSI4 Quantum Chemistry software free download and PSI4 can perform ab initio computations employing basis sets of contracted Gaussian-type functions of virtually arbitrary orbital quantum number. Many parts of PSI4 can recognize and exploit the largest Abelian subgroup of the molecular point group. Table Methods displays the range of theoretical methods available in PSI4.
