摘要	The EPR g factors g(parallel to), g(perpendicular to) and zero-field splitting D of trigonal Cr3+-M+ (M+ = Li+, Cu+, Na+) and Cr3+ -V-B -M3+ (M3+ = Cr3+, In3+, Sc3+, Y3+, Lu3+; V-B denotes the B2+ vacancy) centers in some CsBX3 (B = Mg, Cd; X = Cl, Br) crystals are calculated from high-order perturbation formulas based on the two-spin-orbit coupling parameter model of the 3d(3) ion in trigonal symmetry. From the calculations, these EPR parameters are reasonably explained and the local lattice distortions caused by the charge compensators M+ or V-B are estimated. The results are discussed.
