Defect sites on the TiO 2 (anatase) surface and their formation were modeled on the basis of EPR and IR spectra. In their Full Paper on page 1402 ff., B. C. Gates et al. describe how the sites incorporate Ti 3+ with O 2 − and O − and are marked by their OH groups. They were investigated with a novel probe molecule, [Re 3 (CO) 12 H 3 ], which reacts preferentially with Ti 3+ defect sites, becoming deprotonated, removing most of the oxygen radicals, and healing the defects.
