Raman scattering studies of intermolecular interactions in molecular liquids at high pressure
type: CreativeWork
description: This work is an experimental study of the Raman non-coincidence effect which is the difference between the band centers of the isotropic and the anisotropic spectra. We have studied the C=O symmetric stretching mode of N,N-dimethylacetamide (DMA) and acetone. The band shape parameters are interpreted in terms of a transition dipole-transition dipole coupling mechanism. Theories of the non-coincidence effect due to McHale and Logan have been used to quantitatively study the non-coincidence effect for both DMA and acetone. The influence of the static dielectric constant of the liquid upon the non-coincidence effect is discussed.
