Liaison hydrogène en phase liquide et spectrométrie Raman. III—structure et intensité de la bande ν(OH) d'alcools primaires en solvants inertes

The Raman spectra of methanol in CCl 4 solutions and of isopropanol in freon mixtures were recorded in the OH(OD) stretching region for different concentrations and temperatures. As for pure liquids one observes in the high polymer region a two‐component structure which is shown to originate from intermolecular coupling. Measurements of the scattering activity of the ν(OH) and ν(CH) bands for increasing concentrations shows the invariance of the Raman intensity for the ν(CH) bands but an increase for the ν(OH) band.
