Description

<jats:title>Abstract</jats:title> <jats:p>Using the relative-rate technique, the rate constant for the reaction of OH radicals with isoprene was determined in one atmosphere of air at 298±2 K. Methyl nitrite photolysis in air was used as a source of OH radicals. Ozone and O-atom reactions with isoprene were confirmed to have a negligible contribution on the loss of isoprene. The rate constant relative to three reference compounds yielded (10.4±0.4)×10−11 cm3 molecule−1 s−1 (the uncertainty is 2σ).</jats:p>
