An investigation was made of the annealing behavior of infra-red absorption peaks, at 1052 and 1099/cm, which were due to the C-OB complex. Peaks at 1112 and 1026/cm were attributed to the C-OC complex. It was found that the formation-dissociation reaction of C-OB and C-OC complexes quickly attained a partial thermal equilibrium state at the onset of annealing. On the basis of the mass action law, it was suggested that formation of the C-OB and C-OC complexes involved a single C atom and two or three O atoms, respectively.
