Raman Scattering of H₂O/D₂O Solutions

Abstract

The stretching vibrations of water are perfect characteristics of the hydrogen bond. Studying their frequency shift, changes of intensities, broadening of the bands and appearence of submaxima we can receive very important structural information about the groups involved in H-bonding and about the bond itself. The observed Raman spectra, however, are rather complicated because the OH and OD stretching bands are always superpositions of several bands due to intra- and intermolecular coupling, effect of Fermi resonance etc. The

Key Words:

• stretching vibrations
• H-bond
• isotopic dilution
