Abstract

A laser flash photolysis-resonance fluorescence technique has been employed to study the kinetics of the reaction of atomic chlorine with pyridine (C5H5N) as a function of temperature (215–435 K) and pressure (25–250 Torr) in nitrogen bath gas. At T≥ 299 K, measured rate coefficients are pressure independent and a significant H/D kinetic isotope effect is observed, suggesting that hydrogen abstraction is the dominant reaction pathway. The ...
