摘要	For a d(3) configuration ion, the 120 x 120 complete energy matrix which contains the electron-electron repulsion interaction, the ligand field interaction, the spin-orbit coupling interaction as well as the Zeeman interaction, has been established. By diagonalizing the complete energy matrix, local structure and EPR g factors for Cr3+ ions doped in KA1(MoO4)(2) and RbIn(MoO4)(2) have been investigated, respectively. It is found that the orbit reduction effect is very important to understand the EPR g factors for Cr3+ ions doped in KA1(MoO4)(2) and RbIn(MoO4)(2), and some characteristics of orbit reduction on the EPR g factors are discussed firstly. Simultaneously, by simulating the calculated optical spectra and the EPR spectra data to the experimental results, we obtain the local structure parameters R = 2.043 angstrom, theta = 53.5940 degrees and R = 2.065 angstrom, theta = 56.0434 degrees for Cr3+ ions doped in KA1(MoO4)(2) and RbIn(MoO4)(2), respectively. The calculated results show the local lattice structure of the octahedral Cr3+ centers in KA1(MoO4)(2) and RbIn(MoO4)(2) exhibit an elongation and a compression distortions, respectively.
