摘要	The electron paramagnetic resonance (EPR) parameters (g factors g(parallel to), g(perpendicular to) and hyperfine structure constants A(parallel to), A(perpendicular to)) of the tetragonal Ti3+ centers in ZnSe and CdS0.75Se0.25 semiconductors are calculated from high-order perturbation formulas based on the cluster approach. In these formulas, both the contribution from the spin-orbit coupling parameters of the central 3d(n) ion and that of ligands are considered. The calculated results show reasonable agreement with the observed values. The defect structures of the tetragonal Ti3+ centers in both semiconductors caused by the static Jahn-Teller effect are suggested.
