Rotational state resolved center-of-mass angular scattering and kinetic energy release distributions were analyzed from experimental velocity-map ion images of the HCl (v′=0, j′=0-6) products of the reaction of chlorine with n-butane. It was shown that the angular and kinetic energy release distributions derived from the ion images are very similar to those obtained previously for the Cl plus ethane reaction. It was observed that the angular distributions shift from forward scattering to more isotropic scattering with increasing HCl rotational excitation. It was indicated that the kinetic energy release distributions around 30% of the available energy is channeled into internal excitation of the butyl radical products.
