Ferrari and Robertson noted that, for comparing different fitting parameters of the Raman spectrum, it is fundamental the knowledge of the used fitting procedures. Once we have decided the number of components and their line shapes, we can compare the parameters obtained from a set of Raman measurements, such as those proposed by Sardinha et al., 2020. Since there is no a priori reason to choose a particular function to fit the spectrum, the use of q-Gaussians is good too. As shown by several analyses of Raman spectra with q-Gaussians (see , these functions can be efficiently used due to the power-law of their tails. The q-Gaussian tails have an intermediate behavior, between Lorentzian and Gaussian tails, and Gaussian and Lorentzian tails are rarely observed.
