Radical-molecule Kinetics

Radical-molecule reactions constitute a central component of research in many areas of modern chemistry:

We pursue research in two domains. The first is the development of methods to directly observe the kinetics of radical reactions with molecules in the laboratory using infrared cavity ringdown spectroscopy, laser induced fluorescence, atomic resonance scattering, Fourier transform spectroscopy, and photofragment fluorescence in combination with “wall-less” high-pressure, low temperature flow systems, slit-source pulsed super-sonic jet expansions, and cryogenic optical cells to determine the reaction probability per collision over a broad range of conditions. The second area of work focuses on the theoretical analysis quantifying the entropic and enthalpic barrier to reaction derived from first principles with the objective of both prediction and conceptual understanding of the mechanisms controlling the barrier height.
