The carbon kinetic isotope effect in the reaction between Cl and CH4 (KIE(sub Cl)) has been measured using tunable diode laser absorption spectroscopy to determine (13)CH4/(12)CH4 ratios. Cl atoms were generated by the irradition of Cl2 in static mixtures of Cl2/CH4/N2 or Cl2/CH4/N2/O2. Both methods resulted in a (KIE(sub Cl)) of 1.066 +/- 0.002 at 297 K. The KIE(sub Cl) displayed a slight temperature dependence, increasing to 1.075 +/- 0.005 at 223 K. This result suggests a significant influence of the title reaction on the stratospheric CH4 isotopic composition and may help to resolve discrepancies between measurements of stratospheric (13)CH4/(12)CH4 profiles and laboratory measurements of KIE(sub OH).
