The rate constants for the abstraction of H atoms from CH4, C2H6, and D atoms from C2D6 by C2H (ethynyl) radicals have been determined by using a flash photolysis-kinetic spectroscopic technique. The values obtained, at 297 K, are (1.2 ± 0.2) × 10-12, (6.5 ± 0.4) × 10-12, and (3.1 ± 0.5) × 10-12 cm3 molecule-1 s-1, respectively. The rate constants are independent of added helium over the pressure range 20-700 torr. The kinetic parameters were determined by monitoring the acetylene product spectroscopically using C2H-CF3 as the source of ethynyl radicals.
