摘要: 用拉曼光谱考察了物态变化、水溶液浓度、温度和稀土离子等对癸胺盐酸盐分子构象的影响。结果表明固态标题化合物分子以有序的全反式链构象存在,在大于临界胶束浓度的水溶液中分子以无序的旁式链构象存在;增加浓度、升高温度和添加稀土离子都使得链的扭曲和无序程度增加。

Abstract: The Raman spectra of decylamine hydrochloride (DeACl) were measured in solid stateand in aqueous micellar solutions,and the concentration dependence of molecular conforma-tions was studied.The results showed that in crystalline state DeACl molecules exist inall-trans structure,while in aqueous micellar solutions exist in disorder structure with severalgauche isomers.The order degree of conformations of DeACl decreases with increase of theconcentration, temperature and presence of Pr3+ ions in the aqueous solution.

Key words: surfactant, decylamine hydrochlotide, molecular conformation, Raman spectrum
