We use polarized magneto-Raman scattering to study purely electronic excitations and the electron-phonon coupling in bulk graphite. At a temperature of 4. 2 K and in magnetic fields up to 28 T we observe K-point electronic excitations involving Landau bands with |n|=0 and with |n|=2 that can be selected by controlling the angular momentum of the excitation laser and of the scattered light. The magnetophonon effect involving the E₂₆ optical phonon and K-point inter-Landau-band electronic excitations with |n|=1 is revealed and analyzed within a model taking into account the full kₙ dispersion. These polarization-resolved results are explained in the frame of the Slonczewski-Weiss-McClure model which directly allows the quantification of the electron-hole asymmetry.
