some benchmark atom–diatom reactions of the type ABC→ ABC. For instance, experimental
vibrationally and even rotationally resolved integral or differential cross sections DCS have
been compared with the results of quantum-mechanical calculations for the FH2 Refs. 1–3
and FD2 reactions. 4–6 To the best of our knowledge, however, this high level of
comparison has been reached only for direct abstraction reactions, which are collinearly …
