Vibrational Energy Distribution in the NO Produced by the Reaction of N(4S) with O2.
Abstract
Infrared emission has been observed from NO(v = 2-7) produced by the reaction N(S(4)) + O2 yields NO(v) + O. The apparent NO vibrational energy distribution is different from the distribution initially produced by the reaction owing to stepwise V-V quenching of NO(v) by collision with O2. A time-to-steady-state flowing afterglow experiment has been used, along with data obtained elsewhere, to define the v dependence of this quenching process. After correction for the O2 quenching effect, we concluded that 24.4% of the NO molecules produced in levels v=2 through 7 are produced in v=2 and 15.8, 25.2, 22.6, 7.3, and 4.7% are produced in v = 3 through 7, respectively.
