Water, q-Gaussians and Raman Spectroscopy

Abstract

A large literature exists about the Raman spectroscopy of water. Here we present some articles regarding the spectral region between 2800 and 3800 cm−1, that is the O-H stretching Raman band, and the proposed decomposition obtained by means of Gaussian profiles. We will also approach the decomposition of this region with three q-Gaussian functions, instead of the five Gaussians usually considered. Being the q-parameter of q-Gaussians related to the correlation time of stochastic Kubo modelling of fluctuations, we propose the use of this parameter to characterize the local environments of O-H bonds.
