Abstract

The kinetics of the gas-phase reaction of CH₃O₂ radicals with NO₂ were studied at 295 K in 0.5-14 atm of SF₆ diluent using pulse radiolysis combined with time-resolved UV-VIS spectroscopy. Rate data were obtained by following the loss of CH₃O₂ using a monitoring wavelength of 260 nm. The results were well described using the Troe formula with F_c=0.40±0.09, k₀=(1.46±0.50)×10^-30 cm⁶ molecule^-1 s^-1 and k_∞=(1.81±0.25)×10^-11 cm³ molecule^-1 s^-1. These results are compared to the previous data and discussed in terms of reactivity trends and the atmospheric chemistry of peroxy radicals.
