      abstract     = {[1] The kinetic isotope effects (KIEs) for several
                      ozone-alkene reactions in the gas phase were studied in a 30
                      L PTFE reaction chamber. The time dependence of the stable
                      carbon isotope ratios and the concentrations were determined
                      using a gas chromatography combustion isotope ratio mass
                      spectrometry (GCC-IRMS) system. The following average KIE
                      values were obtained: 18.9 +/- 2.8 (ethene), 9.5 +/- 2.5
                      (propene), 8.7 +/- 1 (1-butene), 8.1 +/- 0.4 (E-2-butene),
                      7.9 +/- 0.4 (1,3-butadiene), 6.7 +/- 0.9 (1-pentene), 7.3
                      +/- 0.2 (Z-2-pentene), 6.7 +/- 0.7 (cyclopentene), 6.1 +/- 1
                      (isoprene), 5.0 +/- 0.7 (1-hexene), 5.6 +/- 0.5
                      (cyclohexene), and 4.3 +/- 0.7 (1-heptene). These data are
                      the first of their kind to be reported in the literature.
                      The ozone-alkene KIE values show a systematic inverse
                      dependence from alkene carbon number. Based on the observed
                      KIEs, the contribution of ozone-alkene reactions to the
                      isotopic fractionation of alkenes in the atmosphere can be
                      estimated. On average this contribution is generally small
                      compared to the impact of reaction with OH radicals.
                      However, when OH-concentrations are very low, e. g. during
                      nighttime and at high latitudes in winter, the contribution
                      of the ozone reaction dominates and under these conditions
                      the ozone-alkene reaction will have a clearly visible impact
                      on the stable carbon isotope ratio of atmospheric alkenes.},
