The effect of the magnetic field up to 3.5 T is investigated on the zero‐phonon luminescence lines of the molecular ions O − 2 and S − 2 in alkali halide crystals at 4.2 K. For the molecules oriented along the twofold axis of the cubic crystal a triplet splitting of the luminescence lines is observed. A model for the selection rules and the polarization characteristic of the Zeeman triplets is developed. The parameters of the excited electronic state can be obtained from the Zeeman triplets.
