Gausian

Program Description:
Gaussian is one of the most popular programs that allow calculations of parameters of molecular systems using methods of quantum chemistry and molecular mechanics and dynamics. Gaussian makes it possible to perform calculations using both ab initio and semi-empirical methods. Calculations can be performed on systems in the gaseous state or solutions, in the ground state or in the excited state.
