✦ Synopsis

A crossed beam chemical reaction, AI(2P1/2,3/2)+ O2(X 3~g )..., AIO(X 2~ +)+ O(3P0,1,2) was investigated by fluorescence imaging techniques. Multiplex detection of speeds and quantum states of both reactants and products has been implemented. The two spin-orbit states of AI atoms display distinctive reactivities towards 0 2 molecules. An electrostatic interaction model was employed to elucidate their dynamic behavior. A barrierless, attractive potential energy surface in the entrance valley of the allowed channel can be inferred from experimental results and model calculations.
