| 摘 要： | 制备了镧系离子Ｎｄ＾３＋与二（２，４，４－三甲基戊基）膦酸（Ｃｙａｎｅｘ２７２）和二（２，４，４，－三甲基戊基）二硫代膦酸（Ｃｙａｎｅｘ３０１）的萃合物，测得了两种萃取物的ｆ－ｆ吸收光谱。用改进后的光谱计算程序分别计算了Ｎｄ＾３＋－Ｃｙａｎｅｘ２７２、Ｎｄ＾３＋－Ｃｙａｎｅｘ３０１两种萃合物行四种对称结构下的吸收光谱。通过计算谱与实验谱的比较，对谱图作了解析和确认。对配合物在溶液中的结构进行了推断

| Abstract: | The computer programm developed in INET for calculating f f transition spectra of lanthanides complex is improved and used for the calculation of Nd 3+ Cyanex272 (bis(2,4,4 trmethylpentyl) phophinic acid)complex and Nd 3+ Cyanex301 (bis(2,4,4 trimethylpentyl) dithiophosphinic acid) complex on the possible complex structure models.By comparison of the calculated results with the experimental date,assignment to the f f hypersensitive spectra of the neodymium complex is given.The most possible structure of Nd 3+ Cyanex272 complex is octahedra with 6 ligands and Nd 3+ Cyanex301 complex structure is cubic with 8 ligands. |
