In connection with local structure, the g factors of 2E state are studied by using complete diagonalization method CDM, with the spinel type crystals ZnAl24:Cr3, ZnGa24:Cr3 and MgAl24:Cr3 as the cases. The slight magnetic interactions, including spin-spin SS, spin-other-orbit SOO and orbit-orbit OO interactions are taken into account in our investigations. Theoretical explanations of g factors of 2E state for ZnAl24:Cr3 have been given. The results show that the sign of g‖E′ for ZnGa24:Cr3 should be negative. And the value of g factors of 2E state for MgAl24:Cr3 have been predicted. It is shown that, the contributions to g factors of 2E state from slight magnetic interactions are appreciable. Compared with the g factors of ground state, the g factors of 2E state are sensitive to the local structure.
