Nitric Oxide Bands near 1 μ in Shock-Heated Air

Abstract

The banded radiation from a strong radiating system has been observed in the near-infrared spectrum of shock-heated air. The dependence of the radiant intensity upon species concentration and temperature, as well as an estimate of the oscillator strength, indicate that the radiation results from transitions between excited electronic states of nitric oxide. This system is shown to be a significant contributor to the infrared emission spectrum of high-temperature air.
