CzH50NO was photolyzed with 366 nm radiation at -48, -22, -2.5, 23, 55, 88, and 120ยฐC in a static system in the presence of NO, 0,, and N,. The quantum yield of CH3CH0, (D{CH3CHO), was measured as a function of reaction conditions. The primary photochemical act is (la) CZHSONO + hv -\* CzH50 + NO an
## 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
