We report a study of the isolated zinc vacancy (V Zn ) in ZnSe using optical detection of magnetic resonance (ODMR) via magnetic circular dichroism (MCD) in absorption. Three MCD bands associated with V Zn - are observed at 1.0, 1.4, and 2.65 eV. The 1.4- and 2.65-eV bands have previously been observed by stress-induced linear dichroism studies. Detection of the band at 1.0 eV provides important confirmation of a previously proposed molecular orbital model for the defect. The MCD-ODMR signals are absorptionlike and disappear for the applied magnetic field along the defect axis
