Abstract

Gas chromatography has been coupled with a pulse radiolysis/ultraviolet spectrometry technique to allow the simultaneous measurement of both intermediates and products of reactions with high sensitivity. Radiolysis of SF6 in the presence of CH4 yields F atoms which react with CH4 to produce CH3 radicals, and these subsequently combine to form C2H6. Both the yields of CH3 radicals (UV absorption) and C2H6 (gas chromatography) were determined. Radical densities calculated from the two analyses have been used to determine the initial F atom yield and the results are in good agreement with a maximum difference of just 5%.
