One obvious way a magnetic field \({\varvec{B}}\) can affect the excitons is that it removes the degeneracies of the orbital and spin angular momentums of the electron and the hole. This results in the splitting (Zeeman splittingZeeman splitting) of the emission/absorption/reflectance spectra. While the conservation of orbital and spin angular momentum makes the transition dependent on the polarization state of the absorbed/emitted photons limiting the number of excitonic transitions.
