一种二茂铁衍生物的一阶超极化率的色散关系
THE FIRST-ORDER HYPERPOLARIZABILITY FRENQUNCY DISPERSION OF A FERROCENYL DERIVATIVE
【摘要】 在含时杂化密度泛函理论的水平上,研究了二茂铁分子的非线性光学性质.计算结果表明,在低能量范围内,二茂铁分子存在一个电荷转移态.利用两态模型计算了分子的一阶非线性超极化率βZ,并讨论了基矢效应和βZ的色散关系,计算结果与实验结果符合得较好.
【Abstract】 The time dependent density functional theory is used to study the nonlinear optical properties of a (ferrocenyl) derivative.There is one charge-transfer state for the (molecule) at low energy regime.The two-state (model) is (formulated) to calculate the first-order hyperpolarizability of the molecule,and the basis set effect and (the) (dispersion) of (first-order) (hyperpolarizability) are discussed.The numerical calculations are in good agreement with the (experimental) (measurement).
