摘要: 采用AM1方法优化分子构型,用ZINDO方法研究了氨基、硝基取代的吡啶系列分子的电子光谱,并在此基础上用自编程序计算了这些分子的二阶非线性光学系数,对取代吡啶系列分子的二阶非线性光学系数的影响因素进行了探讨,并在微观上给予了解释。

Abstract: On the basis of ZINDO methods, according to the sum-over-states(SOS) formula, the program for the calculation of nonlinear second-order optical susceptibilities βijkand βμ has been devised. The structures and nonlinear second-order optical properties of pyridine and pyridine derivatives have been studied. It is concluded that the substitutes have a great influence on the nonlinear second order optical properties of pyridine derivatives. The calculated results have been explained micromechanically.
