The atom-radical reaction Cl + C[sub 2]H[sub 5] [yields] HCl(v) + C[sub 2]H[sub 4] is studied using laser flash photolysis, time-resolved Fourier transform infrared emission spectroscopy and broad band infrared chemiluminescence. The Cl atoms and ethyl radicals are produced from a number of different precursors using one or two lasers. The initial HCl vibrational distribution is determined to be HCl (v=1/2/3/4=0.39 [plus minus] 0.04/0.29 [plus minus] 0.03/0.22 [plus minus] 0.02/0.10 [plus minus] 0.02). The vibrational distribution is characteristic of an addition-elimination mechanism and can be reproduced using modified statistical theories of energy partitioning within the [C[sub 2]H[sub 5]Cl]z[double dagger] intermediate. The time evolution of the HCl(v=4) emission is used to estimate a rate coefficient for this reaction of (3.0 [plus minus] 1.0) x 10[sup [minus]10] cm[sup 3] molecule[sup [minus]1] s[sup [minus]1]. 39 refs., 8 figs., 6 tabs.
