Abstract: On the basis of ZINDO method and according to the sum-over-states(SOS) expression, the program is devised for the calculation of nonlinear second-order optical susceptibilites βijk and studying how different substituents on the phenyl ring attached to the atom silicon influence on the nonlinear second order optical properties of substituted silane series of molecules. The properties of (CH3)3Si——has been studied particularly. The effect of the length of silica chains on the calculated values has been studied too. The regularity summarized from the calculated results has been explained micromechanically.

Key words: Substituted silanes, Nonlinear second-order optical susceptibility, ZINDO-SOS
