Abstract
X-Ray photoelectron spectra of the metal(III)–metal(V) oxides α-Sb2O4 and BaBiO3 are reported. Indications of ‘mixed-valency’ character in the metal core-electron spectra could be found only after careful pretreatment of the samples in situ. Under normal conditions both compounds appear to have surface phases containing just the lower oxidation state.Keywords
