Abstract : Advances made in the study of the dissociation dynamics and product branching ratios of energized transient neutral molecules formed by charge-transfer (DCE) and recombination of cations with free electrons (DR) are reviewed. The results obtained include detailed measurements of the three-body dissociation of H3, O4 and sym-triazine (HCN)3, as well as the product branching ratios for the two-body dissociation of CM5+ and M30+. These results have significance for a number of Air Force applications, one including ion-assisted ignition and combustion for hypersonic vehicle applications. This project aimed to extend our knowledge of the fate of transient neutrals produced in plasma environments while providing fundamental new information on the dynamics of two- and three-body dissociation processes. As noted below, significant successes in the study of DCE processes were achieved, while the efforts at carrying out DR measurements on the last-ion-beam apparatus were not successful.
