  "abstract": "Reactions of fluorine atoms with H₂O and OH play an important role in atmospheric chemistry, the interstellar medium, and combustion processes. In this work, a discharge-flow reactor coupled with an electron-impact ionization mass spectrometer was used to investigate the kinetics of these reactions at a total helium pressure of 2 Torr and over a wide temperature range. The rate constant for the F + H₂O reaction (1) was determined both by absolute measurements conducted under pseudo-first-order conditions, monitoring the kinetics of F-atom consumption in the presence of excess water, and by the relative-rate method (using the F + Br₂ reaction as a reference): k1 = 3.3 × 10⁻¹² × (T/298)1.15 exp(385/T) cm³ molecule⁻¹ s⁻¹ in the temperature range (225–960) K with a total estimated uncertainty of 15% at all temperatures. A U-shaped temperature dependence was observed for the reaction rate constant, consistent with earlier theoretical predictions. The rate constant for the reaction between F atoms and OH radicals (2) was determined from the decays of the OH concentration, monitored under conditions of excess fluorine atoms: k2 = (1.09 ± 0.04) × 10⁻¹¹ exp((447 ± 0.12)/T) cm³ molecule⁻¹ s⁻¹ at T = 225–610 K, where the uncertainties reflect the statistical 2σ precision.",
