✦ Synopsis

Fourier transform infrared spectroscopy was used to establish methyl-d, hydroperoxide

as the dominant product of the gas phase reaction of CD,02 radicals with HO* radicals. Over the total pressure range I O-700 Torr, 100 + 4% of the reaction of CD302 with HO2 proceeds via the channel CD302+HOz+CDXOOH+02.

Quoted errors represent 2~. This result is discussed with respect to previous literature data and to computer models of atmospheric chemistry. As part of this work, the rate constant for the reaction of F atoms with CD4 was determined to be 5.5~ IO-" cm3 molecule-' s-i.
