      abstract     = {The stable-hydrogen kinetic isotope effects (KIEs) for a
                      series of n-alkanes in reaction with chlorine atoms in the
                      gas phase were studied in a 25-L PTFE reaction chamber at
                      298 K. The time dependence of both the stable hydrogen
                      isotope ratios and the concentrations was determined using a
                      gas chromatography pyrolysis isotope ratio mass spectrometry
                      (GC-P-IRMS) system. The following KIE values, in per mil
                      (parts per thousand), were obtained: 39.6 +/- 2.7
                      (n-butane), 28.2 +/- 0.9 (n-pentane), 24.6 +/- 1.0
                      (n-hexane), 24.0 +/- 1.2 (n-heptane), 17.9 +/- 3.3
                      (n-octane), 15.1 +/- 0.7 (n-nonane), and 14.9 +/- 1.8
                      (n-decane). The errors given are the +/- 1 sigma standard
                      errors. These measured values were used to derive
                      structure-reactivity relationship (SRRs), which allow for
                      the calculation of the KIEs for the reaction of n-alkanes
                      with Cl atoms. The results of the calculations agree with
                      the measurements within few per mil or better. The site
                      specific stable hydrogen isotope fractionation effects for
                      methyl groups are approximately a factor of 3 larger than
                      those for methylene group, a finding which is qualitatively
                      similar to site-specific stable hydrogen isotope effects
                      reported in literature for reactions of alkanes with the OH
                      radical. Because n-alkanes with close to natural isotope
                      ratios (i.e. neither artificially labeled, nor enriched or
                      depleted) were used, the KIE data are directly applicable to
                      atmospheric studies. Based on these KIE values, the impact
                      of Cl-atom reactions of the stable hydrogen isotope ratio on
                      alkanes are estimated for different levels of Cl-atom
                      concentrations. On average in the troposphere, the impact of
                      Cl-atom reactions of the stable hydrogen isotope ratio of
                      n-alkanes will be small. However, in regions of the
                      troposphere with high concentrations of Cl atoms, such as
                      the tropospheric ozone depletion episodes during polar
                      sunrise, the impact of Cl-atom reactions is substantial.},
