Laser Induced Fluorescence Studies on C2O and CH Radicals

C2O and CH radicals were quantitatively analysed by LIF in the reaction systems C3O2 + O + H and C2H2 + O + H. The measurements of rate constants and products of the reaction C2O + O as well as C2O + H have been carried out by excimer laser pulse photolysis for the production and by LIF for the detection of the radicals. The results give a basis of a new interpretation of the C2H2 + O + H atom flame system.
