在AM1和INDO/CI方法的基础上, 用自编程序计算了(CH3)2N(C6H4)nCN(n=1→6)系列分子的二阶非线性光学系数β~i~j~k和β~μ并系统地研究了共轭链长对分子二阶非线性光学系统的影响及β~μ对激光场频率的依赖关系(色散效应)

Based on AM1 and INDO/CI methods, using the program for calcns. of the nonlinear optical second-order susceptibilities (bijk), (bijk) and (bm) were calculated for (CH3)2N(C6H4)nCN series mols., n = 1 ?6. A systematic study is reported of the effect of conjugation length on the mol. nonlinear optical second-order susceptibilities and investigated the laser frequency dependences (dispersions) of (bm) are discussed.
