Here we consider the Raman broad scans on minerals of the natrolite group, scans which are published in the RRUFF database. Of the Raman broad scans, we will consider the range between 2000 and 4000 cm -1 , which contains the hydroxyls OH-stretching region. We have already considered this region when we studied the Raman spectroscopy of water; we proposed specifically the decomposition of this large OH-stretching band in components with the q-Gaussian profile (see Appendix). Being the q-parameter of q-Gaussian functions related to the correlation time of stochastic Kubo modelling of fluctuations, we stressed the use of this parameter to characterize the local environments of O-H bonds. We further discussed the OH-stretching band of ice, to understand how the decomposition in q-Gaussians changes in the number of components and values of q-parameters. We have also considered the behavior of the Raman OH-stretching band in the case of the vivianite group of minerals. Here, we will apply the same approach, that is a decomposition of the spectrum in q-Gaussian components, to the scans on zeolites of the natrolite group.
