    • 2• radicals at the G3-(MP2)-RAD level of theory are 32.9 (X = CN) and 40.7 (X =H). The latter value is taken directly from ref 19.

    • β are as defined in Scheme 1. It should be noted that this formula is only correct if the quasi-steady-state assumption holds, if the adduct does not undergo side reactions, and if the fragmentation step is irreversible. In real systems, and particularly in retarded polymerizations, the relationship between the observed transfer coefficient and the individual rate coefficients will be more complex.
