Abstract
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 A1g and B1g modes.
