We have already discussed diamond and graphite Raman spectra in the framework of their decomposition in q-Gaussian Tsallis functions. Diamond has a Raman peak at 1332 cm -1 , corresponding to the vibration of its two Bravais lattices of carbon atoms with respect to each other . The crystalline graphite has a G peak at 1582 cm -1 and a G' (or 2D) peak at 2700 cm -1 . In other carbonaceous materials, such as soot, kerogen, and biochar, besides the G band we find the D1, D2, D3 and D4 bands mentioned by . In Claramunt et al., 2015, we can find a different notation where D is D1, D2 is D', D3 is D'' and D4 is D*. In Sousa et al., 2020, a further D5 component is used (see for instance the Raman spectrum decomposition in their Figure ). Sadezky and coworkers give the following Raman shifts (cm -1 ): ~1580 (G), ~1350 (D1), ~1620 (D2), ~1500 (D3), ~1200 (D4). Let us add ~1700 (D5), according to Here, our aim is that of showing spectra of graphene and graphene oxide, with respect to the graphite spectrum, to understand how many components are required to interpret the fingerprints. Graphene is a two-dimensional honeycomb lattice of carbon atoms that is widely considered for theoretical and applies studies, and for its technological potentials. Raman spectroscopy is considered suitable to characterize it and its related materials . "A large amount of information such as disorder, edge and grain boundaries, thickness, doping, strain and thermal conductivity of graphene" can be obtained from the spectrum recorded under different physical conditions, as discussed by Childres and coworkers. It means that Raman fingerprints must be able to give the proper information, when decomposed in a convenient manner.
