Аннотация:The redox potentials of the trifluoromethyl radical obtained experimentally by the laser photoelectron emission (LPE) method and by solution of the diffusion-kinetics problem involving the adsorption, desorption, electron transfer, and annihilation in the bulk of both the radicals and the products of their electrode reactions were compared. The usefulness of the LPE method for determining the redox potentials and rate constants of redoxreactions of the CF3. radicals was demonstrated.
