某些钕和铒的苯甲酸类配合物的超灵敏跃迁吸收光谱研究

The Hypersensitive Transition Absorption Spectroscopic Investigations of Some Neodymium and Erbium Complexes with Benzoic Acids in Solutions

研究了Ｎｄ^（３＋）和Ｅｒ^（３＋）与苯甲酸、水杨酸、对羟基苯甲酸、邻氨基苯甲酸、对氯苯甲酸和邻菲罗啉配体所组成的配合物在９５％乙醇中的ｆ－ｆ超灵敏跃迁吸收光谱。计算了超灵敏跃迁峰的振子强度Ｐ、电子云伸展比β、共价参数δ和键合多数ｂ^（１／２）。探讨了配合物的共价性。

Abstract The absorption spectra of the f-f hypersensitive transition for LnL_3, LnL_3 phen in 95% EtOH solutions were investigated, where Ln =Nd￣(3+) or Er￣(3+), phen = 1,10-phenanthroline, L =benzoate, salicylate, p-hydroxybenzoate, p-chlorobenzoate or o-aminobenzoate group. The oscillator strength (P)、nephelauxetic ratio
