(a) In this formulation, we do not intend to convey the notion that the configurational structure of the transition state and that of the CT excited ion pair are necessarily the same but only that the energy change in the formation of one serves as a viable model for that of the other. In more rigorous terms, Equation (60) states that alkenes and arenes are subjected to the same perturbations in electrophilic brominations as in the CT transition in the EDA complexes when changes in solvation are taken into account. It must be emphasized that the CT formulation does not require the proof that an EDA complex is (or is not) an intermediate in electrophilic brominations. For a discussion of this point, see footnotes 19 and 20 in [54]
