“…Since the SH parameters of paramagnetic ions depend sensitively on the structural parameters R and θ, it will be useful to determine these parameters with a transition-metal ion as the probe. The EPR study of Ni 2+ ions in CdBr 2 has been done by Fang et al [6]. They calculated the EPR parameters with the high-order perturbation formulae.…”

Based on crystal-and ligand-field theory, double-spin-orbital coupling approach was used to analyze the crystal-field energy levels and spin-Hamiltonian parameters of Ni 2+ ion at trigonal site in CdBr 2 . The local lattice distortion (∆R and τ Ni 2+ ) is estimated from the crystal field parameters; the crystal field energy Hamiltonian was diagonalized in the full basis consisting of 45 wave functions of the Ni 2+ ion. Results of calculations are in good agreement with experimental data. The reasonableness of the theoretical results is discussed.
