The reaction of O(3P) with NO clusters, NO/Ar, NO/He, and NO/CO2 have been studied in a crossed-beam experiment. Both angular distribution and velocity of the chemiluminescent NO2 product were measured. An isotropic distribution was found for (NO)2, while NOAr yielded forward peaking of the scattered products. These results were rationalized based on the lifetime of the collision complex. The upper limits for the NO–NO and the NO–Ar bonds were found to be 6.3±1 and 1.4±0.3 kJ/mol, respectively. The NO · CO2 complexes did not react to produce electronically excited NO2. [ABSTRACT FROM AUTHOR] |
