摘要：
We present an experimental electrophilicity index (?) for the classification of radicals. The ?-scale is based on the equilibrium constant determined for the reversible addition of a radical R-. to an aromatic radicophile (HisNH(2)). This experimental approach is in excellent agreement with the computed global electrophilicity index and serves to validate the latter.
