The fate of the hydroxyalkoxy radical in the OH-initiated oxidation of isoprene [pdf]Paper  abstract   bibtex   
Rate constants for several intermediate steps in the OH- initiated oxidation of isoprene were determined using laser- photolysis/laser-induced fluorescence of OH radicals at total pressures between 3 and 4 Torr at 295 K, The rate constant for decomposition of the hydroxyalkoxy radical was determined to be (3.0 +/- 0.5) x 10(4) s(-1) in this pressure range, which is in fair agreement with previous work. The presence of a prompt alkoxy decomposition pathway was also investigated and found to contribute less than 10% to the total hydroxyalkoxy radical decomposition. The rate constant for the reaction of the hydroxyperoxy radical with NO was determined to be (2.5 +/- 0.5) x 10(-11) cm(3) molecule(-1) s(-1), which is moderately higher than previously reported.
