Some Photochemical Reactions of O3 in the Gas Phase

When a gaseous mixture containing O3 and CO2 of different isotopic composition is illuminated by uv light, the oxygen that is formed has undergone some exchange with CO2. The extent of this exchange has been studied as a function of initial O3 and CO2 pressure, and the influence of foreign gases on it was also studied. It is concluded that O1D is the intermediate which undergoes rapid exchange with CO2, and further that the reaction O1D+CO2⇌CO+O2 does not provide the dominant mechanism for this exchange. The results suggest that at low total pressures exchange takes place by O*+CO2⇌O+CO2* and that at high total pressures, CO3 is formed as an intermediate.
