We report partial densities of states of overlapping bandlike p states and localized d states in several insulating transition-metal oxides which have been determined from frequency-dependent photoemission spectra taken in the range 5-90 eV. We observe that p-band features become weak relative to d-state and satellite features at high frequencies, i.e., at x-ray photoemission frequencies. Partial d-state densities together with a ligandfield description are reported which give a basis for evaluating recent theoretical descriptions of transition-metal oxides. © 1975 The American Physical Society.
