Abstract In the present paper, the 45×45 energy matrix of the 3d² ions in trigonal symmetry with the strong-field-coupling mechanism is established. The forty-five optical energy levels and five EPR parameters (including the zero-field splitting D, g factors g_∥,g_⊥ and hyperfine structure constants A_∥, A_⊥) of ZnO∶V³⁺ cryst are calculated from the diagonalization of this complete energy matrix. The calculated results are in agreement with the observed values. Based on the calculation, it was found that the local structure of V³⁺ impurity center is different from the corresponding structure in the host crystal, i.e., the V³⁺ ion in ZnO does not occupy the exact Zn²⁺ site, but is displaced by ΔZ≈0.003 nm along the c₃ axis. The reasonableness of these results is discussed.
