Individual rovibronic levels of these radicals were measured as a function of time with a tunable dye laser. From these measurements the rate constants for the reaction of each of these vibrational levels with H 2 , O 2 , CO, CO 2 , N 2 , HCN, C 2 N 2 , and CH 4 have been determined. Some enhancement in the rate constant with vibrational energy which could not be ascribed to quenching was observed for O 2 , CH 4 , and H 2 • Only vibrational quenching was observed for HCN, N 2 , CO 2 , CO, and C 2 N 2 • In the CO case the vibrational quenching rate appears to be significantly enhanced by complex formation during the quenching process.

NO also has a high efficiency as a third body in the termolecular recombination reaction between CN and NO. The rate constant obtained in this study for the bimolecular reaction between NO and CN (X2l; +) radicals in v" = 0,1, and 2 are 1.6 ± 0.3X 10-13 ,5.6 ± 0.8X 10-11 , and 6.2 ± LOX 10-11 cm 3 molecule-I S-I, respectively. The termolecular recombination reaction between CN(v" = 0) and NO using Ar as a third body is 6.0 ± 0.6X 10-31 cm 6 molecule-2 S-I, whereas when NO is the third body, the rate constant is 3.2 ± 0.3 X 10-29 cm 6 molecule-2 S-I.
