HYPERSENSITIVE TRANSITION PROBABILITY AND ITS INTENSITY CALCULATION IN LANTHANIDES (III) - ACETYLACETONE-4-METH YL QIUNOLINE TERNARY COMPLEXES

本文测定了钢系(Ⅲ)离子(Nd,Ho,Er)-乙酰丙酮(AA)-4-甲基喹啉(MQ)三元络合物在丙酮溶液中的吸收光谱。由最小二乘法拟合出了Judd-Ofelt参数,并应用Mason 等人提出的动耦合模型进行了强度计算。根据已报导的化合物结构,给出了上述三种络合物的适当结构参数,计算值与实验值吻合的较好。

In this paper, the absorption spectra of the ternary complexes [Ln(AA)4] HMQ(where Ln =Nd , Ho, Er , AA =acetylacetone and MQ=4 -methyl quinoline) in acetone solution are determined, intensity calculation based on the dynamic coupling model is carried out and the structures of the above-complexes are deduced.
