Abstract:
The mechanism of photoprocesses taking place in the region of surface absorption of calcium oxide (hν ≤4 eV) and accompanied by the formation of radical forms of adsorbed oxygen on its surface was investigated. The formation of oxygen radical anions O2- and complexes of molecular oxygen with hole centers [X.O2](g1 = 2.002; g2 = 2.009; g3(1) = 2.015; g3(2) = 2.016) and [Y.O2] (g(parallel-to) = 2.004; g(perpendicular-to) = 2.012) as a result of photoadsorption was detected. The ESR spectra of the X and Y centers are not observed in the 90-300 K range. It was hypothesized that they are O(st)- radical anions in different coordination: (O3c-)st and (O4c-)st, respectively.
