Abstract

Spontaneous Raman scattering spectroscopy was applied to flames of the nitramines HMX, RDX, and nitramine-containing propellant XM39 and to counterflow flames of ammonium perchlorate with methane and ethylene. The best results were obtained for the counterflow flames and for XM39 for which long integration times without the problem of laser-induced breakdown were possible. Temperature was also obtained for XM39 by measuring Stokes and anti-Stokes Raman signals. Results for RDX near its surface was obtained, but due to insufficient spatial resolution, no profiles were measured. A large NO signal was seen with HCN still present. Limited results were obtained for HMX in which laser-induced breakdown was a big problem as well as strong emissions of Na^* and CaOH^*, from sodium and calcium compound impurities.
