The paramagnetic centers of reduced anatase O− (g1=1.999, g2=1.984, g3=1.979) and O3− (g1=2.046, g2=2.008), assigned to the stabilization of photoinduced holes near anion vacancies, have been studied. For the reduced oxide a new type of O2 photoadsorption at h ν>1 eV due to the generation of only electron surface centers has been discovered.
