The optical absorption bands and spin‐Hamiltonian parameters ( g ‐factors g ‖ , g ⊥ and zero‐field splitting D measured by EPR spectra) of Ni 2+ ion at the Cd 2+ (II) site of CsCdCl 3 crystals are calculated by using the method of diagonalizing the complete energy matrix of 3d 8 ions in trigonal symmetry. The calculated results are in reasonable agreement with the observed values. The defect structure of this Ni 2+ impurity center is also estimated from the calculations. The results are discussed.
