Abstract

The UV absorption spectra of the bromomethyl (CH2Br) and bromomethylperoxy (CH2BrO2) radicals have been determined using the flash photolysis technique. CH2Br exhibits the typical absorption band of halomethyl radicals, peaking near 230 nm, and CH2BrO2 exhibits the typical broad absorption of peroxy radicals, with a maximum at 240 nm. Rate coefficients were determined at 298 K for the self-reaction (CH2BrO2BrO2+ CH2BrO2→ 2 CH2BrO+ ...
