Anion-radicals of oxygen O2− and complexes of molecular oxygen with hole centers [X·O2] (g1=2.002, g2=2.009, g31=2−015, g32=2.016) and [Y·O2] (g‖=2.004, g⊥=2.012) have been found to form under CaO irradiation in the range of surface absorption (hν≤4 eV). ESR spectra of X and Y centers have not been observed. They are suggested to be anion-radicals Ost− in various coordinations: (O3C−)st and (O4C−)st, respectively.
