The effect of configuration interaction via crystal field on the intensity of crystal field transitions in tetrahedral Fe 2+ ions has been discussed. The mixing of the excited configurations 3d 5 4p and 3d 5 4f to the ground 3d 6 configuration of the tetrahedral Fe 2+ ion via crystal field results in a parity allowed electric dipole transition between crystal field levels of E and T 2 symmetry. The contribution of such configuration interaction to the oscillator strength of crystal field transition of the tetrahedral Fe 2+ ion in ZnS has been estimated within the framework of crystal field theory using Racah formalism and Richardson functions for the radial integrals. This contribution to the oscillator strength is found to be quite significant and approximately equal to 0.28x10 −4 .
