RRUFF ID R070582 -Let us pass to consider anatase Raman spectrum RRUFF ID 070582 . The Raman data that we will consider are those which have been processed. The following figure show them for an unoriented arrangement, laser 532 nm. The sample is coming from Asker, Akershus, Norway (Source: James Shigley; Owner: RRUFF). "The identification of this mineral has been confirmed by single-crystal X-ray diffraction" (RRUFF). Let us consider the range with the peak at 144 cm -1 . The following figure is showing the processed and the raw data, in semi log scale. In the Fig. , the decomposition is given with three q-Gaussians, the same we did for the Figure . Let us pass to consider the range about 514 cm -1 . Also in this case, the processed data are used. In the Figure we used just one q-Gaussian, to fit onto data. From the discussion given above, we know that two components, with close centers, can exist. Therefore, further fitting must be done. Using two q-Gaussians, the best fit is given in the Fig. . The positions of the two components are determined by the best fit. Let us consider in detail the values of intensity about the peak, as in the plot provided by RRUFF. We can see, near the peak at 514 cm -1 , that two "undulations" at 512 and 517 cm -1 seem being visible. Therefore, maintaining fixed the centre of the second component (magenta colour) at 517 cm -1 , let us investigate how the fit changes, when positioning the centre of the first component (blue colour) at 511, 512, and 513 cm -1 . The results given in Fig. are congruent to the result given in Fig. .
