The Effect of Vibrational Excitation on the Reaction of O(3P) with H2 and the Distribution of Vibrational Energy in the Product OH.

Abstract

The overall rate constant and the product branching rate constants have been measured for the first time for the reaction O(3P) + H2(v = 1) yields OH(v = 1) + H at the rate k(2a) or yields OH(v = 0) + H at the rate k(2b) where k(2) = k(2a) + k(2b). The measurements were made in a flow tube apparatus at T = 302 + or - 2 K at a total pressure of 3 Torr. O(3P) was produced by the titration of active nitrogen with NO. H2(v = 1) was produced by a heated tungsten filament, and its concentration was determined from VUV absorption measurements in the Lyman band system of H2. Absolute concentrations of OH(v = 0) and OH(v = 1) were deduced from laser induced fluorescence in OH in a clibrated fluorescence system.
