The main IR bands of the DL-Homocysteic acid was preliminary assigned. The complexes of DL-Homocysteic acid with Na+, K+, Ca2+ were synthesized. Element analysis and TGA-DTA were used to conclude the compositions of these complexes. The FTIR and FT-Raman spectra were studied to distinguish the different coordination structures. The bands of carboxyl, sulfonate and amino groups are all shifted. The peaks of-CH2- also changed a lot. The results indicated that the H-bonding structures among the moleculars were rearranged. The carboxyl and sulfonate groups of DLH both coordinated with the metal ions. And the coordination structure of C=O group in the three complexes were all monodentated.
对DL-高胱氨酸的主要红外波段进行了初步归属。合成了DL-高胱氨酸与Na+、K+、Ca2+的配合物。采用元素分析和热重-差热分析来确定这些配合物的组成。研究了傅里叶变换红外光谱（FTIR）和傅里叶变换拉曼光谱（FT-Raman）以区分不同的配位结构。羧基、磺酸基和氨基的谱带均发生了位移。-CH2-的峰也有很大变化。结果表明分子间的氢键结构发生了重排。DLH的羧基和磺酸基均与金属离子配位。三种配合物中C=O基团的配位结构均为单齿配位。
