摘要: 采用PM3和INDO/CI理论方法,系统研究了对称取代反式二苯乙烯衍生物的结构和电子光谱.在正确的UV-Vis光谱基础上,预测了双光子吸收峰的位置.自编程序用SOS公式计算了三阶非线性光学系数及双光子吸收截面,并从微观上探讨了不同取代基对双光子吸收截面的影响

关键词: 二苯乙烯衍生物, 电子光谱, 双光子吸收截面

Abstract: The geometry, electronic structures and electronic spectra of trans-stilbene derivatives are systematically studied by PM3 and INDO/CImethods. On the basis of correct UV-Vis spectra, the position and strength of the two photon absorption cross-sections can be predicted. We deviced a program of Sum Over-States expression and calculated the nonlinear third-order optical susceptibilities and two photon absorption cross-sections by it. The influences of various substituents on two photon absorption cross-sections are discussed micromechanically.

Key words: Stilbene derivative, Electronic spectra, Two photon absorption cross section
