Let us consider the article by . "Though there are only covalence bonding and hydrogen bonding interactions, structure of water is rather complex due to the many-body and cooperative effects related to hydrogen bonds" . "Some instructive models were put forward to describe the molecular structure of liquid water, among which the two most representative are the continuum models characterized by water molecules with different hydrogen bonding configurations … , and the mixture (cluster) models describing liquid water as a mixture of distinguishing well defined species … . However, controversy still exists and none of the models proposed is sufficiently satisfactory for interpreting the structure of water" . Raman spectroscopy is suitable for the study of water, being able of providing signals of "intramolecular O-H valence bonds. Moreover, Raman is sensitive to molecular environment, so intermolecular hydrogen bonding interaction could be analyzed. The Raman scattering of O-H stretching vibration at 2800-3800 cm -1 is most informative about structure of water" . "This broad band is usually deconvoluted into several components for analysis, commonly less than six, such as those Gaussian fit with five center frequencies by Carey and Korenowski. Nevertheless, controversy on the quantity and assignment of components still remains" .
