Emission and absorption spectra are measured of several ZnO‐crystals in the region of bound‐exciton complexes near the band gap. From Zeeman‐effect studies up to 8 T at several angles between the c‐axis of the crystal and the magnetic field most of the observed spectral lines are identified. The electron g ‐factor is found to be g e = 1.8, if the exciton is formed with a hole from the A‐band, and g e = 2.1, if the exciton is formed with a hole from the B‐band. The mass of the B‐hole seems to be nearly equal to the mass of the A‐hole.
