Abstract

Experiments were carried out to determine the branching ratio between reaction and relaxation for loss from the |04>^- vibrational state of H₂O in collisions with H atoms. Three sets of experiments were repeated several times with different concentrations of H atoms and H₂O molecules present in the gas mixtures. The results lead to the conclusion that reaction and energy transfer make comparable contributions to collisions between water in the |04>^- state and thermal hydrogen atoms.
