Laboratory angular dependence and the recoil-energy spectrum of the products of the reaction F+C6D6→ D+C6D5F

Abstract
The reaction of fluorine atoms with perdeuterobenzene has been studied by the method of crossed molecular beams. In this reaction a long‐lived intermediate complex is formed. Analysis of the kinetic energy distribution of the products and their angular distribution in space cannot be satisfactorily accounted for by the available statistical theories of unimolecular decomposition. The results of this study can be used to infer that randomization of the internal energy of a molecule is not necessarily rapid relative to chemical reaction.
