His papers deal with molecular structure determinations by electron diffraction, EXAFS and spectroscopic techniques, measurement of the physical and thermochemical properties of the boranes, kinetics of fast reactions and spectral emissions at high temperatures, as studied in shock tubes and in chemical laser systems, and models of nucleation/condensation processes.
"A variety of problems have been investigated by my co-workers, as indicated by the representative list of publications. Those studies focus on molecular dynamics processes that control the rates of reactions (in the gas phase), and on molecular structures of both amorphous solids and extremely fine metallic clusters. We measured heats of condensation of very small clusters and are studying collisional energy transfer rates that are basic to theories of chemical kinetics. We are also measuring rates of very rapid associations/dissociations of donor/acceptor complexes and H-bonds (using a T-jump technique).
We have investigated the mechanism of combustion of boron/carbon/hydrogen compounds using shock tube and flow tube reactors. The mechanisms of oxidation of B2H6, B5H9, and B10H14 have thus been elucidated. We have recorded infrared emissions from shock-heated hydrocarbons to determine whether such processes occur in interstellar space, from which astronomers detected various IR bands in progress rates of pyrolysis of nitro-alkanes."
