Our paper on the spectroscopy of the simplest Criegee intermediate, produced in collaboration with UCI colleague Prof. Benny Gerber, has been published in Phys. Chem. Chem. Phys. We have used broadband absorption and cavity ring-down spectroscopy to measure absolute (and temperature-dependent) absorption cross sections for CH₂OO in the visible/near UV.

Our first paper on the important CH₂I + O₂ reaction has been published in J. Phys. Chem. A. We used cavity ring-down spectroscopy to study the kinetics of IO formation, finding evidence for production both directly and sequentially after first forming CH₂OO + I. The direct mechanism appears to depend on the degree of internal energy of the photolytically generated CH₂I radical; a cautionary tale for laboratory kinetics studies that use this method to generate radical species.
