Methylperoxy radicals were generated by the flash photolysis of azomethane-oxygen mixtures. The observed broadband spectrum of the CH302 radical is similar, but not identical to those reported previously. The CH:302 decay followed second-order kinetics a t high CH:jOz concentrations with k4, = (2.5
## Abstract Pulse radiolysis techniques were used to measure the gas phase UV absorption spectra of the title peroxy radicals over the range 215–340 nm. By scaling to σ(CH~3~O~2~)~240 nm~ = (4.24 ± 0.27) × 10^−18^, the following absorption cross sections were determined: σ(HO~2~)~240 nm~ = 1.29 ± 0
## Abstract Rate constants for the gas‐phase reactions of CH~3~OCH~2~CF~3~ (__k__~1~), CH~3~OCH~3~ (__k__~2~), CH~3~OCH~2~CH~3~ (__k__~3~), and CH~3~CH~2~OCH~2~CH~3~ (__k__~4~) with NO~3~ radicals were determined by means of a relative rate method at 298 K. NO~3~ radicals were prepared by thermal d
Fourier transform infrared spectroscopy was used to identify CHrOCHO and CH,OCH,OOH as products of the gas-phase reaction of CH,0CH202 radicals with HO1 radicals. At 700 Torr and 2952 2 K, branching ratios of k,./k, =0.53 f 0.08 and klb/ k, =0.40\* 0.04 were established. Quoted errors are 2 standard
