A model for the electronic structure of the tungsten impurity in diamond is presented that explains recent photoluminescence results. The model is based on the Ludwig and Woodbury model for interstitial transition-metal impurities in silicon and includes Jahn-Teller coupling, which almost entirely quenches the orbital angular momentum.
