Study of nolinear optical properties of the 4-N-methylstilbazonium salts

The second order nonlinear optical polarizabilities of 4 N methylstilbazonium salts which have noncentrosymmetric space groups in Cambridge Crystallographic Data (CSD) were calculated using MOPAC semiempirical program. The cation planar structures of these salts were also calculated using CSD data. The cation planar structure and substituting group dependencies of their nonlinear optical properties were studied.
