The Zeeman splittings of those luminescence and absorption lines of ZnO are investigated which are due to excitons bound to impurities. Additionally the thermalization of the Zeeman components is studied. The results are discussed in terms of excitons bound to neutral donors and acceptors. The g ‐values for the different lines are determined and discussed. Excited states of the complexes, which are investigated by means of excitation spectroscopy, are identified by their magnetic field behaviour, as being due to a hole from a deeper valence band and excited states of the envelope function.
