Abstract
This spectroscopic and thermodynamic study of aqueous dimethyl sulphoxide (DMSO) suggests that the properties of the system are dominated by direct component interaction. Maximum inter-action occurs in the region of 0.35 mole fraction (DMSO) and “enhancement of water structure” by added solute is absent, except perhaps at very low concentration, < 0.01 mole fraction. The excess enthalpy HE, is compared with literature values.Keywords
