Valence-band X-ray emission spectra of manganese in various oxidation states

Abstract

The Kα_1,2, Kβ_1,3, and Kβ_2,5, Lα_1,2, LβX-ray emission spectra of manganese in MnO, Mn₂O₃, MnO₂, K[MnO₄], MnF₂, and K₂[MnF₆] have been recorded. A knowledge of the Kα_1,2 energy enables the Kβ and L emission spectra to be placed on a common energy scale thus revealing 4p and 3d(+4s) character in the molecular orbitals giving rise to the spectra. The changes in peak intensities and energies are rationalised using a simple molecular-orbital (ligand-field) approach.
