Paper Abstract

Chemiluminescence emitted during the recombination of ground state S atoms was studied in the aim of obtaining a laser emission on the B-X electronic transition of the sulfur molecule. S atoms were produced by reaction of fluorine atoms with hydrogen sulphide in a supersonic expansion. F atoms were produced in a combustor from the reaction of excess NF3 and H2 with He diluent at pressures from 1.3 to 3 atm. Chemiluminescence was observed in the supersonic flow at pressures ranging from 20 to 70 Torr. Experimental spectra were compared to synthetic ones. At a pressure of 70 Torr, a population density of S2(B) close to 108 molecules/cm3 was determined by chemiluminescence intensity measurements. This value is in reasonable agreement with that predicted by our kinetics modeling.
