The results of  ab initio  electronic structure calculations of vacancies and deep donors in wide-gap II-VI compound semiconductors were presented. A comparison with published experimental hyperfine interaction data revealed a satisfactory agreement of both sets of data; except in the case of the F-center in CdTe. It was concluded that this cast serious doubts on the attribution of the F-center.
