The enthalpy of formation, DELTAH(f,0), 0 of the HSO radical has been
determined to be -0.9+/-0.7 kcal/mol from the analysis of high-resolut
ion crossed beam reactive scattering experiments on the reaction O(3P)
+ H2S-->HSO + H at different collision energies. The results are comp
ared with previous experimental and theoretical estimates.
