For the two considered samples (RRUFF R060277 and R070582), the fitting with q-Gaussians is giving relevant results. For the case of range about 515 cm -1 , and its decomposition in A1g and B1g modes, results are encouraging for further investigations. In any case, the q-Gaussians are giving better results, when compared to Lorentzian and Gaussian functions. Let us consider two q-Gaussians. Also in this case, we can decompose the profile of the peak with two q-Gaussians. The file is available in the Crystallography Open Database (COD), . The original data for this entry were provided by IUCr Journals, . It is told that "file may be used within the scientific community so long as proper attribution is given to the journal article from which the data were obtained." For the article, see Howard et al., 1991, "Structural and thermal parameters for rutile and anatase". The Raman measurement device location was the Arizona University. The device was a Thermo Scientific Nicolet Almega XR. Excitation laser wavelength was 780 nm. The direction of polarization is given as unoriented.
