Gas Diagnostics Utilizing Laser Induced Raman Scattering

Abstract

The feasibility of using various techniques to determine the chemical and thermodynamic state of individual species in a flowing gas mixture is discussed. It is theoretically shown that, using the Raman scattering technique, species concentration can be determined for individual molecular constituents. Also, the static temperature of the gas and the vibrational temperature of molecular species can be obtained. The apparatus used for the present Raman scattering measurements is described and experimental data on the species concentrations of oxygen and nitrogen in air are presented. Limitations of the technique are also discussed.
