The Ti-O bonds around the reduced center undergo a remarkable elongation (0.05 Å). In the case of the hole, the localization on an O 2− site, which assumes O − character, implies a larger trapping energy (0.74 eV) compared to the electron. The polaronic elongation of the O-Ti bonds is very large (0.1–0.2 Å).
