Far ultraviolet photolysis of carbon dioxide

Carbon dioxide in the pressure range of 50-600 Torr has been photolyzed at 1470 Å. An initial quantum yield of Φ(CO) = 1.0 was observed. The O 2 /CO ratio was 0.35 ± 0.02. While the O 2 /CO ratio remained constant, the rate of CO formation decreased significantly with an increase in the photolysis t...

Description
Summary:Carbon dioxide in the pressure range of 50-600 Torr has been photolyzed at 1470 Å. An initial quantum yield of Φ(CO) = 1.0 was observed. The O 2 /CO ratio was 0.35 ± 0.02. While the O 2 /CO ratio remained constant, the rate of CO formation decreased significantly with an increase in the photolysis time. Such a lowering of the conversion rate is attributed to a light attenuation due to solid deposit being formed on the lamp window.
