Abstract
Optical absorption, power rotary and circular dichroism of crystals of the sillenite family Bi12MxI20(M- elements I-VIII of groups or their combination) were measured. The t1-2e charge transfer transition of the [VO4]3- tetrahedral complexes is found to make a negative contribution to the optical rotation of the vanadium sillenite. We present a model, which takes into account a negative contribution from the charge-transfer transitions of [MO4]n- complexes to the optical rotation in Bi12MxO20 crystals. It was found that M vacancies and crystal field transitions of 3d- elements contribute significantly to the circular dichroism of sillenite crystals.
