Abstract
The chemiluminescent nature of the reaction N + O2 → NO + O followed by N + NO → N2 + O has been investigated in the steady state through detection of characteristic infrared radiation emitted by NO molecules. Both Δv = 1 radiation at 5.4 μ and Δv = 2 at 2.7 μ exhibit linear dependence on O2 pressure. In the case of the overtone, low-resolution spectra are obtained at several O2 pressures, and it is shown that under the experimental conditions reported here the spectra should closely reflect the initial vibrational distribution of the NO molecules as they are formed. From the spectral results we are able to estimate an overtone quantum efficiency for the reaction N + O2 → NO‡ + O. Depending upon the experimentally reported value of the rate for this reaction, the quantum efficiency is between 0.2 and 0.5.
