ResumoRecent chemical activation studies of isomerizations of alkyl and alkenyl radicals involving 5, 6, and 7 member ring complexes are shown to be consistent with earlier thermal studies and support the conclusion that the A-factors of these reactions are "low", i.e. substantially less than 10 11 s −1 . A possible explanation, consistent with transition state theory, is given in terms of configurational entropy.
