硝酸稀土甘氨酸固体配合物的红外光谱研究

THE IR SPECTRAL STUDIES ON RE(NO_3)_3 WITH GLYCINE COMPLEXES

稀土与甘氨酸作用形成固体配合物的研究工作已有许多。但用稀土硝酸盐与甘氨酸作用生成固体配合物的工作尚未见文献报道，而红外光谱的研究也未开展，本工作在水相中制得了Ｌａ、Ｃｅ、Ｐｒ、Ｎｄ、Ｓｍ、Ｅｕ、Ｇｄ、Ｔｂ、Ｙ共９种稀土硝酸盐与甘氨酸固体配合物，测量了配合物的ＦＴ－ＩＲ光谱，对其主要红外吸收带进行了归属，同时也对配合物配位键性质进行了探讨。

There have been mang reports onthe research work of the compounds formed by rare earth and glycine: but the report onthesolid compounds formed by rare earth nitrates and glcine is not yet available, and theresearch of their IR spectrats is not conducted.In this work, nine solid compunds (La.Ce.Pr.Nd.Sm.Eu.Gd.Tb.Y) in water phase are produced.Their FT-IR spectrals are studied ,their main IR absorbing belts classified,and meanwhile,their coordination bonds explored.
