Let us consider the part of the Raman O-H stretching band at lower frequencies. In the Figure in Baschenko and Marchenko, 2011, we can note that the component centered at 3070 cm -1 , is within the tail of the component centered at 3230 cm -1 : this fact is suggesting that the use of a q-Gaussian function, which has a tail which is fatter than that of a Gaussian function, could be interesting for fitting this part of the band, instead of using two Gaussian components (in the following Figure , the q-Gaussian turns out to be the blue profile with q=1.275). For the spectra previously considered , the fitted q-Gaussian functions are successfully in several cases, for instance graphite, ChemRxiv1, SERS spectra, ChemRxiv2, and so on, SSRN.
