Abstract
The hydrogen trioxy radical (HO<sub>3</sub>) has been proposed as an intermediate in several important chemical reactions and relaxation processes involving OH in the atmosphere. In this work, the gas-phase infrared action spectrum of HO<sub>3</sub> is obtained in the OH overtone region, along with the product state distribution of the OH fragment following dissociation. The highest observed OH product channel sets an upper limit for the HO−O<sub>2</sub> binding energy of 6.12 kcal mol<sup>-1</sup>. The experimental stability of HO<sub>3</sub> and derived equilibrium constant imply that up to 66% of atmospheric OH may be converted into HO<sub>3</sub> in the tropopause region.
