Principal Research Interests
Our research is directed towards understanding how molecules react and the factors that determine the rates and products of chemical reactions. The principal areas of research involve the spectroscopy, photochemistry, reaction dynamics, and reaction mechanisms of ions in the gas phase.
The primary experimental technique used in our research is Ion Cyclotron Resonance (ICR) spectroscopy. We have assembled continuous wave, pulsed, and Fourier-transform instruments. These are coupled with a variety of light sources, including conventional arc lamp/monochromator, argon ion/dye laser/Ti-Sapphire laser, cw CO2 infrared laser, and pulsed TEA CO2 infrared lasers.
Among our current projects are attempts to understand the basis of gas-phase ion reaction dynamics. In particular, we are developing statistical and other models for reaction rates. We make use of the analysis of potential surfaces, for example, to define and characterize nucleophilicity in negative ion reactions without solvent. We are attempting to understand the nature of steric effects and hydrogen bonding and the effects of solvent on these phenomena. We make use of multiple photon infrared absorption to activate reactants or possible intermediates in reactions and observe their unimolecular decomposition.
Finally, we use visible photons to effect detachment of electrons from negative ions. By studying the details of the electron photodetachment process (onsets, threshold shapes, resonances, fine structure, etc.) we learn about electron affinities, electronic structure in ions, excited electronic states in ions, and vibrational structure and spin orbit splitting (or triplet-singlet splitting) in the final state neutrals. |
