In nature we can find the titanium dioxide in three crystalline modifications: rutile (tetragonal), anatase (tetragonal) and brookite (orthorhombic). In these lattices, each titanium ion is surrounded by a distorted oxygen octahedron , and references therein). Here we consider, besides those from literature, the data coming from RRUFF collection , and from Raman Open Database, developed in the framework of project SOLSA H2020 (El Mendili et al., 2019). In the following plots, data are generally given in red and the best fits in green: q-Gaussian components are shown in blue and magenta colours. The misfit is also proposed in the lower part of the images. Data and best fits are given as functions of integers n (equally spaced points), for the x-axis, which is representing the Raman shift. A convenient scale is used for the y-axis (intensity axis). Semi log plots are also proposed.
