DTIC ADA080121: Reactions and Energy Transfer of Excited Molecules.

The effect of reagent rotation is investigated for the reaction K + HCl = KCl + H and found to be more important than a similar amount of translational energy. Rotation decreases reactivity. Electronic excitation of NO in the reaction NO + O3 = NO2 + O2 was shown to roughly be equivalent to ground state reactivity. Reaction is apparently enhanced by rotation of the NO molecule. The origin of these effects is not yet understood. (Author)
