Fitting q-Gaussians onto Anatase TiO2 Raman Bands

In previous studies, we used the Tsallis q-Gaussian functions for the analysis of Raman spectra, providing several successful examples. . Here we apply q-Gaussians to anatase TiO2 Raman spectra from literature, and from RRUFF and ROD databases.. We will discuss, in particular, the Raman band about 515 cm⁻¹, and its decomposition in A_1g  and  B_1g modes.
