|Abstract:||Flames of metal oxidation chemical reactions, where metal vapors of alkali or alkali-earth atoms react with strong oxidizers such as the halogen or nitrous oxide molecules, have been examined for their stimulated and spontaneous infrared radiative properties. Various thermodynamic, spectroscopic, and thermochemical parameters for the reaction product salt vapors have been calculated in order to characterize energy transfer mechanisms and radiative emissions. Infrared spontaneous emission spectra have been calculated and a computer program written for least-squares determination of vibrational population distributions from experimental spectra.
High temperature nozzle systems have been designed and operated for fast flow and mixing of metal vapors and oxidizers. Experimental reaction chambers and associated detection optics have been employed in measurements involving continuous wave infrared lasing potential, infrared spectrophotometric gain, infrared chemiluminescence, and associated visible chemiluminescence.
Observed dominance of black body infrared emissions has been explained in terms of condensation phenomena occurring because of reaction region pressure-temperature conditions. New visible chemiluminescence from the Mg + Cl(,2) reaction has been recorded and partially assigned. The implications of very high temperatures extremely rapid vibrational energy transfer rates, and numerous vibration to electronic energy mechanisms have been discussed with respect to infrared radiative processes.
