Raman frequencies and polarizations and infrared frequencies of water and heavy water have been obtained, and the intermolecular vibrations of water have been related to a five-molecule hydrogen-bonded C2v model consistent with x-ray data. Observed variations of the integrated Raman intensity of the 175-cm—1 hydrogen-bond-stretching vibration, with variations of temperature, have been interpreted in terms of the five-molecule model. That interpretation leads to reasonable values for the enthalpy of hydrogen-bond formation. Effects of electrolyte addition on the intensity of the 175-cm—1 band are also described.
