We have completed a three-year program of research into the properties of nitrogen-rich heterocyclic compounds, all nitrogen compounds and silicon carbide clusters with adatoms. The research projects all include a very strong blend of experiment and state-of-the-art theory, obtaining structural and thermochemical properties of unusual and unstable species. The experimental approaches include anion photoelectron spectroscopy and detailed investigations of ion-molecule reactions using flowing afterglow and drift tube reactors. These techniques together provide complementary information that yields quantitative thermochemical information on very unstable species. The ability of the flow reactor to study minute quantities of ions also allows the investigation of speculative, possibly low-yield pathways to these energetic molecules. Specifically, we are studying the ion chemistry and thermochemical properties of a number of nitrogen-rich heterocyclic compounds and their radicals. Time-resolved photoelectron imaging measurements yield new insight into the ultrafast dynamics.
