A thermochemical equilibrium calculation is compared with the experimental results of active mass spectrometric sampling of a high-temperature NF/sub 3/-CH/sub 4/-H/sub 2/-CS/sub 2/ flame. The predicted flow rate of the products HF, CS, N/sub 2/, and CS/sub 2/ is found to agree with the experimental data. The presence of S among the product species is inferred from a second experiment, in which the flux from the high-temperature combustor was extracted through a supersonic nozzle and mixed with a second supersonic stream containing He and O/sub 2/. The flow rate of the reaction product CO determined during the latter experiment is compared with the flow rate predicted by a kinetics model of the chain reaction between CS and O/sub 2/ initiated by small amounts of S. It is suggested that such a CS and S generator coupled with a supersonic mixing nozzle could be utilized to construct a completely chemical CO laser of any desired output power.
