Potential constants and molecular electro-optical parameters

A review and analysis of the main quantum-mechanical calculation methods of certain physical properties of small molecules-methods, based on solution of the Schroedinger equation in different approximations to the wave function, which are used nowadays, are presented. Nonempirical variants of calculation of potential constantse polarizabilities, derivatives of dipolar momentum and polarizabilities according to generalized nuclear coordinates have been considered. The accUracy of the results and a perspective to increase it are evaluated. Tables of the most interesting calculation results from the viewpoint of their applicability and principle use are given
