摘要： 研究了Nd3+和Ho3+的内、外消旋-双(苯基亚砜)乙烷配合物的固体和溶液(非水溶剂)的电子光谱,分析了可见范围的电子光谱并计算了光谱参数(β、b1/2、δ和Ωλ)和f-f跃迂强度,指出了"超灵敏"跃迁的振子强度与配合物的共价程度及配位数相关。

Abstract: The electronic spectra of the Nd3+and Ho3+complexes with diastereoisomeric meso and rac forms of bis(phenylsulfinyl)ethane in the solid state and in the nonaqueous solvent were studied. The electronic spectra in the visible region are analysed. The-spectral parameters(β, b1/2,δ and Ωλ) and oscillator strengths are calculated arid discussed. It is shown that the oscillator strength of the hypersensitive transitions is related to the degree of covalency and the coordinaton number of the complexes.
