Quantitative experimental studies were carried out to measure the degree of electronic state excitation produced in reactions of metal atoms with various oxidizers. The objective is to discover reactions that could lead to an electronic transition chemical laser. Flames of the alkaline earth metals Mg, Ca, Sr, and Ba reacting with F2, Cl2, NOCl, and N2O have been studied at pressures from one to three torr using an evaporation oven as the metal atom source. Diffusion flames of encapsulated metals, consisting of the carbonyls or alkyls of Ni, V, Al, Zn, and Sn, reacting primarily with F2 were studied at pressures from 0.5 to 5 torr. The Ba N2O reaction was found to have a photon yield of 10, and is a good candidate for laser studies. Emission spectra are reported and discussed.
