CO2 photolysis revisited

Abstract

Measurements have been made of the absolute oxygen atom yields from CO2photolysis at 1470 and 1302–1306 Å; in both cases the yield is unity. The CO generation rates have also been measured in these two wavelength regions, and they are proportional to the oxygen atom generation rates; by implication the CO quantum yields are thus also unity. The CO deficiencies observed in earlier work on this subject are probably caused by heterogeneous processes.
