✦ Synopsis

Abstract

A direct kinetics study of the product‐forming channels of the reaction of isoprene‐derived hydroxyalkylperoxy radicals with NO has been performed at 100 Torr pressure and 298 K using the turbulent flow technique with high‐pressure chemical ionization mass spectrometry for the detection of reactants and products. For comparative purposes, a similar study was also performed for the reaction of 1‐ and 2‐butene‐derived hydroxyalkylperoxy radicals with NO. The measured hydroxyalkylnitrate product channel branching ratios were determined to be 0.061, 0.068, and 0.070 for the 1‐butene, 2‐butene, and isoprene systems, respectively. The results are compared to previous measurements of the hydroxyalkylnitrate‐branching ratios for these systems, and the atmospheric significance of the results is discussed. © 2007 Wiley Periodicals, Inc.
