The ZFS parameters D , F , and a of Fe 3+ in Al 2 O 3 are evaluated by taking the spin‐ orbit interaction as the perturbation to the crystal‐field and the electrostatic potentials. Calculations are carried out up to fifth order and show a good convergence. Meanwhile, the optical fine structure is analyzed by diagonalizing the complete energy matrices. The obtained results are in good agreement with the experimental data reported in the literature.
