摘要：
The results of our experimental study of the kinetics of formation of O-2((1)Sigma) molecules in energy-exchange reactions O-2((1)Delta) + I((5)p, P-2(1/2)) and O-2(a, (1)Delta) + O-2(a, (1)Delta) are presented. The ratio of rate constants was obtained for these reactions (4800 +/- 300). Setting the rate constant of the deactivation of O-2((1)Sigma) molecules on CO2 molecules at 4.1 center dot 10(-13) cm(3)/s, we evaluated the rate constants for these reactions at a temperature of approximately 330 K: (1.7 +/- 0.2) center dot 10(-13) and (3.6 +/- 0.5) center dot 10(-17) cm(3)/s, respectively.
