An interpretation of the 4 T 1 (1) → 6 A 1 luminescence and 6 A 1 → 4 T 2 (1) absorption spectrum of Mn 2+ in ZnS is presented. These transitions show only two closely spaced zero‐phonon lines which is in contrast to static crystal field theory. It is shown that strong Jahn‐Teller coupling to E‐vibrations, which fully quenches the linear spin–orbit interaction, can account for the observed zero‐phonon line doublets and the size of the splittings. The results apply also to Mn 2+ in CdS, GaP, and ZnSe, where similar zero‐phonon doublets have been observed.
