The reactions of the biogenic organic compounds isoprene and 2‐methyl‐3‐buten‐2‐ol (MBO) with ozone have been investigated under controlled conditions for pressure (atmospheric pressure) and temperature (293 ± 2 K), using FTIR spectrometry. CO was added to scavenge hydroxyl radical formation during the ozonolysis experiments. Reaction rate constants were determined by absolute rate technique, by measuring both ozone and the organic compound concentrations. The measured values were k 1 = (1.19 ± 0.09) × 10 −17 cm 3 molecule −1 s −1 for the reaction between ozone and isoprene and k 2 = (8.3 ± 1.0) × 10 −18 cm 3 molecule −1 s −1 for the reaction between ozone and MBO. © 2004 Wiley Periodicals, Inc.
