Raman OH stretching spectra were measured for a range of alcoholic LiCl solutions in the glassy state. The sharp OH stretching Raman peak due to alcohol molecules weakly hydrogen bonded to chloride ions shifts to lower wavenumbers with an increase in the molecular weight of an alcohol. A simple model calculation suggests that the shift can be mainly ascribed to the change in the mass of an alkyl group of the alcohol rather than a change in the strength of the hydrogen bond.
