Because of needs for understanding the chemical kinetic mechanism in chlorocarbon molecule incineration, we have recently completed studies on the thermal decompositions of COCl{sub 2}, CH{sub 3}Cl, CH{sub 2}Cl{sub 2}, CCl{sub 4}, and CF{sub 3} Cl. The shock tube technique combined with atomic resonance absorption spectrometry (ARAS), as applied to Cl atoms, has been used to obtain absolute rate data for these reactions. In all cases, the decompositions are nearly in the second-order regime. Theoretical calculations, using the Troe formalism, have been performed. In these calculations, both the threshold energies for decomposition, E{sub o}, and the energy transferred per down collision, {Delta}E{sub down}, are varied parametrically for best fitting to the data. The latter quantity determines the collisional deactivation efficiency factor, {beta}{sub c}.
