ResumoManganese compounds have many applications in areas such as catalysis, electrochemistry, and metallurgy, among others. Distinguishing between the various chemical states of manganese is an important aspect of research in many of these areas. It has been shown that the different chemical states of manganese can be identified with XPS through the Mn 2p3/2 peak positions, Mn 2p1/2 satellite–Mn 2p1/2 peak separations, Mn 3s multiplet splittings, or Mn Auger parameters. To date, however, all of these values have not been available in a single reference. In this study, XPS has been used to obtain core level, Auger, and valence band spectra for a commercial, high purity MnO2 powder. This submission provides a reference that contains all of the Mn XPS data necessary for the identification of MnO2 and also provides information that may be useful for the analysis of other Mn compounds.
