✦ Synopsis

Absolute rate coefficients for the reactions of the hydroxyl radical with ethane (kl, 297-800 K) and propane (kz, 297-690 K) were measured using the flash photolysis-resonance fluorescence technique. The rate coefficient data were fit by the following temperature-dependent expressions, in units of cm3/molecule-s: kl(T) = 1.43 X 10-14T1.05exp (-9ll/T) and k z ( T ) = 1.59 X 10-15T1.40 exp (-428/T). Semiquantitative separation of OH-propane reactivity into primary and secondary H-atom abstraction channels was obtained.
