摘要
研究了Nd3+和Er3+分别与色氨酸、本丙氨酸、缬氨酸、脯氨酸、咪唑和苯并咪唑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。计算了超灵敏峰的振子强度P、电子云伸展比β、共价参数6和键合参数b1／2。探讨了配合物的共价性。
The absorption spectra of the f-f hypersensitive transition for LnA3, LnA3. B in 95%EtOH so-lutions were investigated, where Ln = Nd3+ or Er3+, B = Imidazole, Benzimidazole, A = L-Trypto-phan, L-Phenylalanine, L-Valine, L-Proline. The oscillator strength (P ) , nephelauxetic ratio (β) covalent parameter (δ) and bonding parameter(b1/2) were calculated from spectra data. The covalentdharacter of the complexes were also discussed'
