Paper Abstract

The technique which makes it possible to simultaneously determine the temperature T and the partial pressure of carbon dioxide in a vibrationally equilibrium gas mixture at atmospheric pressure by using the spectral distribution of the unsaturated absorption coefficient at the oscillation lines of a tunable CO2 laser is presented. The results of model calculations of the influence of H20 molecules upon the precision of determining temperature and partial pressure of CO2 in C02:N2:H20=10:80: 10 mixture at full pressure 1 atm and temperature T=l000 K have given.
