Summary

Pulsed laser photolysis coupled with time-resolved UV-absorption monitoring of CH3CO•radicals was applied to obtain the rate constant, k 1, for the reaction CH3CO•+ HBr → CH3C(O)H + Br (1); k 1(298 K) = (3.59 ± 0.23 (2σ))x10-12cm3molecule-1s-1. Utilization of k 1in a third law procedure has provided the standard enthalpy of formation value ofDf H°298(CH3CO•) = -10.04 ± 1.10 (2σ) kJ mol-1in excellent agreement with a very recent IUPAC recommendation.
