Laser Raman and infrared studies on hydrotropes and related materials

Abstract

Hydrotropes, which are molecules used as solubilising agents in aqueous systems, are closely related to surfactants and micelles in many of their properties. Information on the aggregation of these molecules in aqueous systems and their interaction with other molecules in solution, can be obtained conveniently by laser Raman Spectroscopy. In the present paper Raman spectral studies on the hydrotrope sodium butyl monoglycol sulphate (NaBMGS), is presented and discussed with reference to spectral changes in solution and interaction with probe molecules.
