Abstract

Novel modeling and sensitivity analysis techniques are used with experimental data obtained from discharge flow-resonance fluorescence experiments to evaluate the product branching ratio of OH + H₂CO. Two channels are considered: the H-atom abstraction reaction (R2) to form HCO and H₂O; and the addition reaction (R17) followed by rearrangement and decomposition to form HCOOH and H. The rate constant values obtained at 298 K are k_R2 = (7.75 ± 1.24) × 10^-12 cm ³/molecule s and k_R17 = (0.2_-0.2 ^+0.8) × 10^-12 cm³/molecule s. The results demonstrate that the reaction proceeds almost exclusively via the H-atom abstraction pathway.
