摘要: 本文以XL-200型超导NMR谱仪对镧系离子与L-组氨酸配合物进行了一系列的研究,测得微酸性条件下的顺磁诱导位移,对这些诱导位移进行分析计算,得到了各磁性核的配合物生成位移、接触位移和准接触位移,同时以准接触位移为依据,对配合物结构进行模拟,获得了有关的结构参数.并对镧系离子在磁学性质上的特征进行了讨论.

Abstract: The paramagnetic induced shifts of the coordination compounds of lanthanide with L-histidinc have been measured in weak-acidic condition by XL-200 NMR spectrometer. The induced shifts were separated into compound formation shifts, contact shifts and pseudo-contact shifts. The structures of coordination compounds were simulated based on the pseudo-contact shifts and some structure parameters have thus been obtained. In addition, the magnetic characteristics of lanthanides were discussed in this paper.
