Abstract
The gas phase reactions18OH + H16O2 → H218O + 16O2 (1a)18OH + H16O2 → 16OH + H18O16O (1b)were studied at room temperature in a discharge flow reactor with far infrared laser magnetic resonance (LMR) detection of 16OH, 18OH and H16O16O. The formation of 16OH in the course of the reaction was observed. The absolute rate constant for the overall removal of 18OH in excess of H16O16O was determined. Each run was accompanied by a control experiment replacing the initial 18OH by the same amount of 16OH. From these experiments a branching ratio is obtained ofk1a/( k1a + k1b) = 0.52 ± 0.08
