The UV absorption spectra of the bromomethyl (CH2Br) and bromomethylperoxy (CH2BrO 2) radicals have been determined using the flash photolysis technique. CH 2 Br exhibits the typical absorption band of halomethyl radicals, peaking near 230 nm, and CH2BrO 2 exhibits the typical broad absorption of pe

The ultraviolet-absorption spectrum and the self-reaction of CHF202 radicals have been studied in the gas phase at 298 K using the pulse radiolysis technique and long-pathlength Fourier transform infrared spectroscopy. Absorption cross sections were quantified over the wavelength range 220-280 nm. T
Plash photolysis kinetic absorption spectroscopy was used to investigate the gas phase reaction between hydroperoxy (HO,) and methylperoxy (CH302) radicals at 298 K. Due to the large difference between the self-reactivities of the two radicals, firstor second-order kinetic conditions could not be ma
