Kinetics of HCCL + NOx reactions

The kinetics of reactions of HCCl with NO and NO2 were investigated over the temperature ranges 298-572 k and 298-476 k, respectively, using laser-induced fluorescence spectroscopy to measure total rate constants and time-resolved infrared diode laser absorption spectroscopy to probe reaction products. Both reactions are fast, with k(HCCl + NO) = (2.75 ± 0.2) × 10-11 cm3 molecule-1 s-1 and k(HCCl+NO2) = (1.10 ± 0.2) × 10-10 cm3 molecule-1 s-1 at 296 K. Both rate constants displayed only a slight temperature dependence. Detection of products in the HCCl + NO reaction at 296 K indicates that HCNO + Cl is the major product with a branching ratio of φ = 0.68 ± 0.06, and NCO + HCl is a minor channel with φ = 0.24 ± 0.04.

Dissociations of Gas-Phase CHClF and CHCl2 Radicals and Cations following Collisional Electron Transfer. A Variable-Time Neutralization-Reionization and ab Initio Study

Variable-time neutralization-reionization mass spectrometry is used to generate CHClF(.) and CHCl2(.) radicals and to study their unimolecular dissociations within 0.4-4.1 μs.Loss of Cl(.) is a major dissociation of CHClF(.) following collisional neutrali

On the Reactions of CHCl(X1A') with NO and O2

The reactions of CHCl(X1A') with NO(X) and O2(X) were investigated at room temperature in the gas phase using a quasistatic vacuum reaction cell.CHCl was generated by pulsed exciplex laser photolysis of CHClBr2 and detected directly by laser induced fluorescence (LIF).Reaction rates were determined from concentration profiles of CHCl under first order reaction conditions ( ): k(NO) = (9 +/- 3)x1012 cm3/mol s k(O2) 10 cm3/mol s.The reactivity of CHCl versus NO and O2 is compared to the reactivities of other triatomic carbenes.
