Having obtained good results with q-Gaussians for graphite and carbonaceous materials, and because of some previous investigations using the q-BWF to include the phonon confinement in the Raman spectrum, here we start applying q-BWF line shapes to the Raman spectroscopy of naturally occurring van der Waals (vdW) heterostructures. Of them, graphite and molybdenite are the best known naturally occurring materials . It was the exfoliation of these two natural van der Waals minerals, that "shaped a whole new field of research", that is that of the 2D materials . Today, most materials are synthetic, but nature is providing plenty of van der Waals materials that can have relevant applications. Let us start considering the molybdenite, that is, the molybdenum disulfide, MoS2.
