摘要：

The hydrogen atom products of the OH A (2)Sigma(+) (upsilon = 0) + H-2 --> H + H2O quenching reaction have been characterized by Doppler spectroscopy. The translational energy distribution of the products is bimodal, with the two components accounting for approximately 3% and 40% of the 4.72 eV of available energy.
