| 中文摘要 | In this paper, the high-order perturbation formulas based on the two spin-orbit coupling parameter model for the EPR g factors g(parallel to), g(perpendicular to) and hyperfine structure constants A(parallel to), A(perpendicular to) of 3d(9) ion in tetragonal tetrahedral crystals are established by a molecular orbital approach. In these formulas, the contributions to EPR parameters from both the spin-orbit coupling parameter of central 3d9 ion and that of ligands are included. By use of these formulas, the EPR parameters Delta g(parallel to)(= g(s) - g(parallel to)), Delta g(perpendicular to)( = g(s) - g(perpendicular to)), A(parallel to) and A(perpendicular to) for Ni+ in AgGaS2 and AgGaSe2 crystals are calculated. The calculated results show good agreement with the observed values. The importance of the contribution from the spin-orbit coupling of ligands to various EPR parameters is discussed.
