Comparison between infrared and raman band profiles in the absence of rotational relaxation in the liquid phase: ν(OH) of methanol in acetonitrile

Abstract

In the case of weakly hydrogen bonded systems OH…B it has been shown that the ν(OH) IR and Raman band profiles are not identical. The origin of this difference is discussed in terms of changes in the dipole moment and polarizability derivatives with intermolecular forces
