Abstract:

Photoionization mass spectrometry was used to investigate the rates and mechanisms of several gas phase reactions. Several hydrocarbon free radicals were observed for the first time in low pressure flames. Two new radicals C3H3, HC2O were discovered and studied kinetically. The reaction of oxygen atoms and acetylene was studied extensively. The direct observation of free radicals lead to the development of a new technique to measure very fast rate constants, the approach to steady state methods. Two mechanisms and rate constants were shown to be important for the reaction of methyl radicals and oxygen molecules.
