IR spectra of oxygen adsorbed on SnO2 with and without lattice defects have been studied. At low temperatures oxygen is adsorbed on defect SnO2 in two forms of O 2 − . This supports the earlier results obtained by ESR. The low-temperature forms of adsorbed oxygen (unrevealed in ESR spectra) were detected on defectless SnO2. High-temperature forms of adsorbed oxygen appear in the IR-spectra as bands due to vibrations of the cation-oxygen bond.
