Abstract

Different compounds are created when chlorine molecules and vinyl radicals react. Over the lowest doublet potential energy surface, a potential mechanism for this reaction has been put forth at the CBS-QB3 and CCSD(T)/CBSB3 levels of theory. According to theoretical kinetics studies, the dominant product in this system is CH2Cl-CHCl. One deep potential well and 10 distinct channels make up the doublet surface for the reaction in the title. The Single-well multichannel RRKM method along with steady-state approximation for the corresponding intermediate (RRKM-SSA) have been used to estimate the rate constants for the formation of the most likely products that pass through the energized pre-reaction adduct over the temperature and pressure ranges of 300 to 3000 K and 5 to 10,000 Torr. The pressure dependence of various channels is also examined.
