Abstract: On the basis of AM1 and INDO/CImethods, we devise the program for the calculation of nonlinear second-order optical susceptibilities βijk and perform systematic theoreticalstudies on the nonlinear optical second-order properties of azobenzene series molecules ,i.e.on the basis of ,we induced different donors on the left sideof phenyl ring, and different acceptors on the right side of phenyl ring,and examined therule of β variation.The regularity summarized from the calculated results has been explainedmicromechanically.Finally,a molecule having a big nonlinear second-order optical susceptibility has been designed.

Key words: Azo dyes, NLO second-order property, Molecular design
