Raman spectroscopic evidence for pre-micellar association in 4-bromobutyric acid solutions

Abstract

Infrared and Raman spectra of 4-bromobutyric acid are reported. Raman spectra of the ν(C-Br) region for a range of concentrations below the critical micelle concentration have been interpreted in terms of $\text{gauche}$ C₄ - C₃ linkages becoming more dominant upon pre-micellar association. The results demonstrate the viability of using bromine substituted species in Raman studies of micelle formation.
