Abstract
The flow photolysis of ozone-oxygen-atmospheric gas mixtures at 253.7 nm was used to determine the relative rate constants for the deactivation of O(super 1 D) and O2(super 1 sigma). The ozone partial pressure was in the range O - 30 mTorr, the oxygen partial pressure was up to 900 times the ozone pressure and a third gas was present at a partial pressure of up to 10 Torr making a total pressure under 11 Torr. The fraction of ozone decomposed was kept less than 0.10. The primary photochemical reaction produces the 1D state of atomic oxygen which then transfers its energy to O2 producing the 1 sigma state of molecular oxygen.
