Abstract:In this paper, we investigate the applicability of the Valence Effective Hamiltonian (VEH) method to calculations of theoretical molecular linear polarizabilities by the Sum-Over-States (SOS) methodology. Test calculations are presented on the polyene series. They indicate that the method gives qualitatively the same trends asab initio small basis sets calculations.Dedicated to Professor J. Koutecký on the occasion of his 65th birthday
