Temperature Dependence on the Low and High Frequency Raman Scattering from Liquid Water.

Abstract

Bose-Einstein corrected Raman spectra of water were measured between 3.5 and 89.3 C. The low frequency Raman spectra lead to a value of 2.6 + or - 0.1 kcal/mole for the rupture of the hydrogen bonds. It is in good agreement with measurements obtained by other techniques. Absolute Raman spectra in the OH stretching region yield a precise isosbestic point at 3425/cm. This is indicative of an equilibrium between hydrogen bonding and non-hydrogen bonding classes of interaction. Difference spectra in this region establish the presence of the equilibrium and indicate that the OH oscillator strength is conserved in terms of the two classes of bonding.
