摘　　要：On the basis of the crystal field theory, the formulae of the EPR g factors of three order perturbation with b 2g  ground state for 3d 9/3d 1 ions at rhombic tetrahedral clusters (AX 4) n- have been obtained. Using these formulae, The authors investigated the EPR g factors of the crystals Cs 2CuCl 4 and T 2CuBr 4. The calculation results agree with the experimental findings.On the basis of the crystal field theory, the formulae of the EPR g factors of three order perturbation with b 2g  ground state for 3d 9/3d 1 ions at rhombic tetrahedral clusters (AX 4) n- have been obtained.
