Shifts in the oxygen K-emission band from some fifty simple oxide compounds were studied as part of a program to evaluate soft x-ray spectroscopy as a tool for characterizing thin layers on metals. The main peak tends to shift to shorter wavelengths as the valence of the coordinating cation increases. For oxides of transition metal element one can determine the cation valence from the O-K-alpha position. For the oxide of the non-transition metals the oxygen peaks tend to be relatively narrow and exhibit little or no resolved fine structure. For oxides containing highly charged cations the OK-beta band becomes a well-resolved feature on the long wavelength side of the main peak.
