Abstract
Estimates have been made of Fe2+ term splittings in axial crystalline fields. It is found that all three long-wave bands in the optical spectrum are due to Fe2+ → Fe3+ charge transfer, while the splitting of 5T2g and 5Eg occurs in low-symmetry fields. Experimental evidence is presented for these calculations.
