Notes:
The gas phase reaction of OH radicals with hydrogen iodide (HI) has been studied using a Laser Photolysis-Resonance Fluorescence (LP-RF) apparatus, recently developed in our group. The measured rate constant at 298 K was (2.7 ± 0.2) × 10-11 cm3 molecule-1 s-1. This rate constant is compared with the ones of the reactions OH + HCl and OH + HBr. The role of the reaction OH + HI in marine tropospheric chemistry is discussed.In addition, the LP-RF apparatus was tested and validated by measuring the following rate constants (in cm3 molecule-1 s-1 units): k(OH + HNO3) = (1.31 ± 0.06) × 10-13 at p = 27 and 50 Torr of argon and k(OH + C3H8) = (1.22 ± 0.08) × 10-12. These rate constants are in very good agreement with the literature data.
