. 2) Let us stress that the use of a single q-Gaussian can produce a fit which is far better than that we can obtain with a Gaussian or a Lorentzian function. However, if we need to investigate the behavior of the wings of isolated peaks, generalized asymmetric and pseudo-Voigt functions are required to have specific results. 3) In , we show excellent results in the deconvolution of the spectra obtained by means of q-Gaussians. It is easier to fit a spectrum when different bands are present, than to fit it in the case when just an isolated band is present. In other words: it is more difficult to fit an isolated peak, but this case is fundamental to understand the intrinsic behavior of the lineshape. 4) Voigt functions cannot represent the cases here considered for sure. 5) The conclusion is that we need the q-Gaussians for fitting Raman bands.
