We present a comprehensive study of the band structure of two- andthree-dimensional hexagonal layered materials using Landau Level optical Halleffect spectroscopy investigations, employing graphene and graphite as modelsystems. We study inter-Landau-level transitions in highly oriented pyrolyticgraphite and a stack of multilayer graphene on C-face 6\textit{H}-SiC, usingdata from reflection-type optical Hall effect measurements in the mid-infraredspectral range at sample temperatures of $T=1.5$~K and magnetic fields up to$B=8$~T. We describe a comprehensive dielectric polarizability model forinter-Landau-level transitions, which permits analysis of the optical Halleffect data. From their magnetic field dependence we identify sets of H- andK-point inter-Landau-level transitions in graphite and sets ofinter-Landau-level transition from decoupled graphene single, and coupledgraphene bi-, tri-, and quad-layer for the multilayer graphene stack. Forinter-Landau-level transitions in decoupled graphene single-layers and H-pointtransitions in graphite we observe polarization mode preserving behavior,requiring symmetric magneto-optical contributions to the correspondingdielectric tensors. Inter-Landau-level transitions in coupled graphene layersas well as K-point transitions in graphite exhibit polarization mode mixingbehavior, requiring antisymmetric magneto-optical contributions to thecorresponding dielectric tensors. From the circular-polarization-averagedinter-Landau-level transition energies and the energy splitting between right-and left-handed circular polarized inter-Landau-level transitions we determinethe model parameters in the Slonczewski-Weiss-McClure band structureapproximation for two- and three-dimensional hexagonal layered materials, withgraphene and graphite as examples.
