Abstract : The possibility of measuring species concentration in high- temperature air by microwave spectroscopy is considered. The species selected for consideration are molecular oxygen, which has transitions in the region from 52 to 68 Gc, and nitric oxide with transitions around 150 Gc. The feasibility appears marginal, but this evaluation is based on many approximations and assumptions and further work is required for definitive conclusions.
