Abstract

The measurement of the intra- and inter-molecular dynamics of aqueous dimethyl sulfoxide (DMSO) solutions using optical heterodyne-detected Raman-induced Kerr effect spectroscopy were presented. The longer diffusive relaxation time constant τ₂ was assigned to DMSO reorientation. The starter time constant τ/₁ was assigned to water reorientation. Results showed that polarizabilities of DMSO permit to estimate the anisotropic Kerr signal for an isolated DMSO molecule.
