✦ Synopsis

The reaction of O p P ) with 1-C4Hs was examined in the presence of CO which scavenges HC) radicals to produce CO,. From the CO, quantum yield, an upper limit to the efficiency of HO production in the reaction of O(3P) with I-CdHs was found to be 0.02 at boi h 298" and 473OK.

Since the classic work of Cvetanovid [l], it has been accepted that O ( 3 P ) reacts with olefins exclusively by addition to the double bond. Recently however, Huie et al. have examined the reaction over the temperature range 190-298"K, which extended their previous work 131 done over the temperature range 259493°K. When the two sets of data were combined, a nonlinear Arrhenius plot was obtained. Huie et al.

[2] interpreted this nonlinearity to two processes, addition to the double bond and abstraction of an H atom by the O ( 3 P ) atom.

## 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
