    • The symmetrical 2-fold sinusoidal potential from which eqn (3) was derived will not be exact for unsymmetrical radicals, 22 and 27-29. The torsional potentials of the radicals 26-28 derived from DFT computations (see text and ESI) were all 2-fold and approximately sinusoidal. The computed torsional potential for 29 contained an additional but minor minimum. Errors introduced from this source are not likely to be more serious than those arising from the "classical limit" approximation itself

    • For each of the unsymmetrical 5-member ring radicals there are, of course, two alternative 5-exo-ring closures that could produce the same cyclized radical. However, the correlation is expected to apply for the faster of the two The volatile allyl alcohol, formed from 6b-d and 7, evaporated during solvent removal Intramolecular H-abstractions probably do not occur because no rapid 1,5-H-translocations are open to alkoxycarbonyloxyl radicals from precursors of type 5 or type 6. Although possible, intramolecular 1,4-H-abstractions are generally much slower and the benzyl radicals so obtained from intermediates of type 15, and the allyl type radicals so obtained from 19, would have been readily detectable by EPR
