▎ 摘　　要

We show how the magneto-phonon resonance, particularly pronounced in sp(2) carbon allotropes, can be used as a tool to probe the band structure of multilayer graphene specimens. Even when electronic excitations cannot be directly observed, their coupling to the E-2g phonon leads to pronounced oscillations of the phonon feature observed through Raman scattering experiments with multiple periods and amplitudes determined by the electronic excitation spectrum. Such experiment and analysis has been performed up to 28 T on an exfoliated four-layer graphene specimen deposited on SiO2, and the observed oscillations correspond to the specific AB stacked four-layer graphene electronic excitation spectrum.
