Abstract
Weak spectral features in the Raman spectrum of water vapour associated with the v 2 and 2v 2 vibrations have been observed. These features have been reproduced by computer simulation using the results of high resolution absorption spectral analyses. Relative intensity measurements allow the determination of the cross section, depolarization ratio and ratio of the two non-vanishing second-order irreducible spherical tensor components for v 2. From these quantities, the principal components of the v 2 derived polarizability tensor have been determined, and these results, as well as the mean derived polarizability tensor for the 2v 2 transition, are considered under the bond polarizability theory.Keywords
