The fate of the hydroxyalkoxy radical in the OHP-initiated oxidation of isoprene

abstract

• AbstractRate constants for several intermediate steps in the OHinitiated oxidation of isoprene were determined using laserphotolysis/laserinduced 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) 104 s1 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) 1011 cm3 molecule1 s1, which is moderately higher than previously reported. 2002 Wiley Periodicals, Inc.
