Employing state‐of‐the‐art and practical peak‐fitting and background modeling methods (active approach), we obtained high quality fitting of the photoemission spectrum of Co 2 p in cobalt spinel. The concurrent analysis of both 2 p 3/2 and 2 p 1/2 branches played a fundamental role. It revealed various Auger features that interfere with the main photoemission lines. It was possible to accurately reproduce the corresponding composition (Co 3 O 4.0 ± 0.25 ) and to report the relative intensity of the various multiplet/satellite peaks including the associated uncertainties.
