Notes:
Unpaired electron spins on radicals in solution can hop between several molecules of the same species. Two types of hopping process are considered: (1) intermolecular hopping, where the unpaired spin can jump to many molecules and (2) intramolecular hopping, where it jumps between the two equivalent sites of a connected dimer. In both cases the hopping process leads to characteristic changes of the magnetic field dependence of the triplet recombination yield observed by reaction yield detected magnetic resonance (RYDMR) experiments. This allows one to discriminate between many- and two-site hopping and to determine the value of the hopping rate.
