Valence band of liquid water Raman scattering: some peculiarities and applications in the diagnostics of water media

A short analysis of the results of our research on peculiarities of water Raman scattering spectra and of their applications in the diagnostics of water media is presented. The results of using a new approach for research on water Raman scattering spectra, i.e. the method of artificial neural networks for spectra treatment and for the solution of inverse problems in water media diagnostics, are also presented. This technique allowed us to improve the accuracy of water temperature determination (error 0.3 °C) by exploiting the temperature dependence of valence band parameters. However, no peculiarities of this dependence in the vicinity of 20, 36 and 76 °C, reported by others, were discovered. Copyright © 2000 John Wiley & Sons, Ltd.
