Absolute and relative rate techniques were used to study the reactivity of Cl atoms with cyclohexanone in 6 Torr of argon or 800 950 Torr of N2 at 295 2 K. The absolute rate experiments gave k(Cl + cyclohexanone) = (1.88 0.38) 10 10, whereas the relative rate experiments gave k(Cl + cyclohexanone) = (1.66 0.26) 10 10 cm3 molecule 1 s 1. Cyclohexanone has a broad UV absorption band with a maximum cross section of (4.0 0.3) 10 20 cm2 molecule 1 near 285 nm. The results are discussed with respect to the literature data.
