Raman spectral examinations of water‐alcohol interactions with various types of polyhydric alcohols at different levels of concentration were conducted. The parameters chosen for study seem to indicate that, at the concentrations used, polyols have little or no effect on the molecular structure of water. Further, the new band in the isotropic spectra of salt solutions reported for various alkali metal halides is absent from the spectra of polyhydric alcohols. It is concluded that polyols have less effect on the molecular organization of water than small but charged entities such as ions.
