Abstract

Potassium permanganate, KMnO4, is a d0 compound as TiO2. It has been shown that TiO2 has satellite peaks in the core level spectra due to many body effects in the photoemission process. It is interesting whether manganese compounds of d0 have the satellite peaks or not. This submission provides information that may be useful for the discussion of the photoemission process. The intrinsic satellite peaks are distinct from the inelastic scattering energy loss peaks. In this study, XPS core- and valence band-level spectra including the energy loss parts were taken for the in situ fractured surfaces KMnO4 crystals. The crystals grown from the aqueous solution were used because the sample is light sensitive.
