摘要: 计算了苯胺、硝基苯、邻硝基苯胺、间硝基苯胺、对硝基苯胺及2,4-二硝基苯胺的二阶非线性光学系数β2,讨论了取代基间电荷转移对分子二阶非线性光学系数的影响。得知β′=βaddct不是很好的计算公式,但考虑取代基间的电荷转移对β的贡献仍有其价值。

Abstract: The nonlinear second-order optical susceptibilities βx of some substituted benzenes: aniline, nitrobenzene, o-nitroaniline, p-nitroaniline and 2,4-dinitroaniline were calculated. Then the effects of charge transfer between substituted groups on molecular nonlinear second-order optical susceptibilities were discussed. The conclusion is thatβ′=βaddct is not a good formula for the calculation of β, although the idea of contribution of charge transfer between substituted groups for β is still a considerable useful concept.
