Abstract

Weak magnetic fields are found to increase the bulk ion-radical yield from a triplet radical pair, in temperature-viscosity region where cage recombination occurs. The results are consistent with Noyes' theory of geminate reactions and a hyperfine coupling mechanism for spin inversion leading to quenching.
