The g factors g(parallel to), g(perpendicular to) and hyperfine structure constants A(parallel to), A(perpendicular to) for two trigonal Co2+ centers Co2+ in Cd2+(I) and Cd2+(II) sites) in CsCdCl3:Co2+ crystals are calculated from the high-order perturbation formulas based on the cluster approach. In the calculation, the contributions from covalency effect and configuration interaction effect are considered and the parameters related to both effects are obtained from the optical spectrum and the structure data of the studied system. The results are in good agreement with the observed values.
