摘要: 迄今未见任何稀土氨基酸络合物的ESR波谱报道,本文在合成Gd3+分别与甘氨酸、β-丙氨酸、谷氨酸、天冬氨酸和天冬酰胺五种氨基酸络合物的基础上,测定了不同温度下,水溶液、粉末及分子筛吸附样品的ESR谱,讨论了络合物中晶体场强,对称性及成键特性。

Abstract: ESR spectra of Gadolinium (Ⅲ) complexes with amino acids have not been reported up to now. Synthesis of five amino acid-Gd(Ⅲ) complexes is reported in this paper. The ESR spectra of their powder samples and that of Gd (Ⅲ) complexes in Y zeolite were determined at various temperatures. The crystal field, symmetry and the bonding character of these complexes are discussed.

Key words: Amino acid, Gadolinium (III) complexes, ESR spectra
