Sa. Kandel et al., ANGULAR-DISTRIBUTIONS FOR THE CL-]HCL+C2H5 REACTION OBSERVED VIA MULTIPHOTON IONIZATION OF THE C2H5 RADICAL(C2H6), The journal of physical chemistry. A, Molecules, spectroscopy, kinetics, environment, & general theory, 102(13), 1998, pp. 2270-2273
The title reaction has been studied by observing the ethyl radical pro
duct by means of resonance-enhanced multiphoton ionization (REMPI) tha
t proceeds at 242 nm via highly dissociative Rydberg states. The metho
d of core extraction was employed to measure the speed and spatial ani
sotropy distributions of the C2H5 product from which the differential
cross section and the internal energy distribution of the products wer
e deduced. The C2H5 product exhibits broad scattering that peaks sidew
ays, and the internal modes of this product are not significantly exci
ted. These results agree closely with these found from a previous stud
y of the title reaction in which the HCl product was detected by REMPI
under the same conditions. Additionally, we report REMPI detection of
the propyl radical product in the analogous Cl + C3H8 reaction.
