Relation between 2p X-ray photoelectron and Kα X-ray emission spectra of manganese and iron oxides

The high resolution Mn and Fe K alpha X-ray emission spectra (XES), and Mn and Fe 2p X-ray photoelectron spectra (XPS) for manganese and iron oxides were measured, The spectra were compared with those of [MnO4](-), [Fe(CN)(6)](4-) and [Fe(CN)(6)](3-) ions, As the electronic structure of the latter compounds do not change with electron hole creation in the cure levels, satellite peaks due to charge transfer are not observed in the 2p XPS spectra, and the peak profiles of metal 2p XPS and K alpha XES are governed by the exchange splitting between 2p and valence electrons. The metal 2p XPS spectra of the oxides had satellite peaks, but the XES spectra had no satellites. FWHMs of the metal 2p(3/2) main peaks of the compounds being low spin states are smaller than those of metal K alpha(1) XES spectra, However, FWHMs of Mn 2p(3/2) Of the manganese oxide were nearly equal to those of Mn K alpha(1) XES spectra, and those of Fe 2p(3/2) XPS spectra of the iron oxides are greater than those of Fe K alpha(1) XES spectra.
