A spectrophotometric investigation has been made of the copper environment in copper-doped ultra-high purity sphalerite. A d-d absorption band was observed at 11,000 cm (super -1) , the spectral position and intensity of which are indicative of octahedrally bound copper(II). No tetrahedrally bound copper was detected. It is concluded that the copper is located interstitially.
