Absolute reactive cross sections for the reaction OH+CO→H+CO2

摘要: Using laser photolysis and vacuum-UV laser-induced fluorescence “pump-and-probe” technique, the microscopic dynamics of reaction OH+CO→H+CO 2 was studied at different center mass energies. Translationally excited OH radicals were generated by H O a wavelength 248 nm 193 nm, nascent atoms produced in with room temperature CO molecules detected under single collision conditions Lyman-α transition. With calibration method using S (248 nm) HCl (193 as source well-defined atom concentrations, following absolute cross sections measured: δ R (0.82 eV)=(0.3±0.1) (1.13 eV)=(1.2±0.3) . The experimental results are compared full-dimensional (6D) quasiclassical trajectory studies carried out global potential energy surface, derived from ab initio calculations.
