Abstract:Criegee intermediates (chem{R_1R_2COO}) are understood to be critical intermediates in the ozonolysis of alkenes, but their high reactivity has traditionally made them very difficult to study directly. Although the smallest Criegee intermediates have now been generated in the laboratory using a diiodomethane photolysis scheme, numerous questions still remain about the product branching ratios of Criegee intermediates formed directly from ozonolysis. This talk will discuss our recent detection of the simplest Criegee intermediate, chem{CH_2OO}, in the ozonolysis of ethylene, using Fourier transform microwave spectroscopy and a modified pulsed nozzle. Nine other product species of the reaction were also detected, in abundances that qualitatively support the published mechanisms and rate constants.
