The intensities I c and I a respectively of chemiluminescent emission by CO 2 in the O+CO reaction and by NO 2 in the O+NO reaction have been measured from 200 to 300 °K in a fast flow system. Both I a and I c were found to obey an expression of the type I = I 0 [O] [XO], where I 0 was independent of total pressure over a similar range of low pressures. I 0c was found to depend on the nature of the inert gas M used as carrier. I 0a was found to have a small negative temperature coefficient similar to that of the overall reaction O + NO + M -> NO 2 + M . (1 a ) I 0c had a positive activation energy of 3.7 + 0.5 kcal/mole. The pre-exponential factors of I 0a and I 0a were similar and the rate constant at 293° K for the overall combination O + CO + M -> CO 2 + M (1 c ) was less than 0.002 of that of reaction (1 a ). The chemiluminescent reactions proceed via three body processes, since I 0 and k 1 showed dependences on the nature of M for both the O + NO and O + CO reaction. A considerable fraction of the product molecules formed in both reactions is produced through the excited state from which emission occurs and the negative temperature coefficients of k 1a and I 0a are apparently due to redissociation of excited NO 2 molecules from vibrational levels close to the dissociation limit. O + NO are stabilized into an excited state of NO 2 by a third body. This state, which is the one responsible for the predissociation in the NO 2 absorption spectrum , crosses the state from which emission occurs and into which excited NO 2 molecules undergo rapid radiationless transitions. A similar radiationless transition occurs between triplet CO 2 molecules formed in the initial combination step and the singlet state from which emission to the ground state ( 1 E + g ) takes place. Spin reversal in the O + CO reaction is therefore not a rate-controlling step for light emission nor for combination, and the activation energy observed for I 0c is due to the presence of an energy barrier over which the CO 2 molecule must pass to reach the stable triplet state.
