摘要: 在AMI和ZINDO方法基础上, 按完全态求和公式计算了分子二阶非线性光学系数βijk, 对苯配系列衍生物分子的二阶非线性光学性质进行了系统的理论研究.即在分子R'C6H4NHC6O2NH2R基础上, 分别改变取代基R和R', 研究取代基变化时产变化的规律性, 对计算结果所反映的规律性在微观上给予了合理的解释.

Abstract: On the bases of AM1 and ZINDOmeth0ds, according to the sumover-states ex-pression, the nonlinear second-order optical susceptibilities βijk of a series of molecules ofbenzoquinone derivatives have been calculated. Systematic theoretical studies on the nonlin-ear optical second-order properties of benzoquinone series molecules have been performed, i.e. on the base of R'C6H4NHC6O2NH2Rindependently changing Rand R', the rule of varia-tions of β has been examined. The regularity summarized from calculated results has beenexplained micromechanica1ly.

Key words: Benzoquinone derivative, Nonlinear second-order optical property, ZINDO-SOS
