摘要	High-order perturbation formulae for the electron-paramagnetic-resonance (EPR) parameters g-factors (g(x), g(y) and g(z)), and zero-field splitting (ZFS) parameters D and E of the ground state (3)A(2g) of 3d(8) ions in the crystal field (CF) with rhombic symmetry (C-2v) have been derived in the strong field scheme, using the molecular orbital (MO) scheme for the first time, and applied to the investigation of Ni2+ (3d(8)) ions doped in LiCl crystal. In the derivation, both the contributions from all the crystal field excited states and the most important charge-transfer (CT) excited states to the EPR parameters are taken into account. The relations between the EPR parameters and the local structure parameters are established, and the defect of Ni2+-V-c center are determined quantitatively. In addition, the Clebsch-Gordan (C-G) coefficients used to construct wavefunctions in the second-kind coordinate system are calculated and given. (C) 2012 Elsevier B.V. All rights reserved.
