Abstract
A series of pure and mixed chromium standards has been analysed by x‐ray photoelectron spectroscopy in order to obtain a sufficiently homogeneous and self‐consistent set of spectral parameters to be used in the resolution of complex spectra. Additional information was obtained about the stability of the various species under Ar ion bombardment. The results relevant to potassium chromate and dichromate, chromous acid, chromium (III) oxide, hydroxide and nitrate are described and compared critically with those in the published literature.
