β¦ Synopsis
The bimolecular rate constants for electron transfer from aromatic triplets to polyaryl carbocations are large and diffusioncontrolled even in the limit of high exothermicity. In some cases, although the exothermicity of energy transfer is comparable to that for electron transfer, the latter dominates over the former.
