The false-color (3D type) image of the intensity of the Raman spectra of monolayer MoS2 versus both peak positions and polar angles is plotted. It shows that the strongest E2g1+ and E2g1− peaks appear at different angles, reflected as the alternation of the maxima of the intensity within the frequen...
