Notes:
Chromium (III) 2p photoelectron spectra show strong satellites on the high-binding-energy side of the main photoelectron peaks. In the case of Cr 2p spectra, the satellite of the Cr 2p3/2 peak strongly overlaps the Cr 2p1/2 peak. As a result, a virtual three-peak spectrum is obtained. In order to analyse the spectral features of the Cr 2p photoelectron peaks, we propose a fitting formalism for Cr(III) 2p spectra that is consistent with a relaxation model. This model allows for the possibility of two different final-state screening conditions of the photoinduced core hole. Considering these two final states, Cr 2p spectra basically can be interpreted by a superposition of two 2p doublets. X-ray contributions arising from the Kα3,4 lines were also taken into account, as well as the existence of OH groups on the surface of Cr2O3 samples. Additionally, a rather pragmatic approach for fitting the Cr L3M23V Auger spectral region was used to obtain further spectral parameters (e.g. α′) that do not depend on charging.
