## Abstract Pulse radiolysis techniques were used to measure the gas phase UV absorption spectra of the title peroxy radicals over the range 215โ340 nm. By scaling to ฯ(CH~3~O~2~)~240 nm~ = (4.24 ยฑ 0.27) ร 10^โ18^, the following absorption cross sections were determined: ฯ(HO~2~)~240 nm~ = 1.29 ยฑ 0
The gas phase reaction of the hydroxyl radical with the unsaturated peroxyacyl nitrate has been studied at 298 2 2 K and atmospheric pressure. The OH-MPAN reaction rate constant relative to that of OH + n-butyl nitrate is 2.08 2 0.25. This ratio, together with a literature rate constant of 1.74 X c
