The effect of reagent electronic energy on the dynamics of chemical reactions: A high-resolution crossed beam study of O(3P,1D)+H2S

Crossed beam reactive scattering studies of the H displacement reaction of both ground 3P and excited 1D oxygen atoms with H2S show that the reaction dynamics changes dramatically upon electronic excitation: while the reaction of O(3P) is direct, that of O(1D) proceeds via a long-lived complex.
