TEA CO2 LASER-INDUCED TELOMERIZATION CHEMISTRY IN CONVENTIONAL AND WAVE-GUIDE PHOTOREACTORS

Experimental approaches to the chemical synthesis of gas phase radical s by IR multiple photon excitation of polyatomic molecules are conside red. The transversely excited atmospheric (TEA) CO2 laser-induced telo merization reaction of C2F4 and CF3I was studied in conventional and w aveguide photolysis reactors. The difference in the product distributi on in the two cases can be explained in terms of the various competing rate constants and the concentration of the perfluoroalkyl radicals g enerated in the irradiated volume.
