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
