Abstract
The influence of external magnetic fields on the spin dynamics and rec ombination reaction yield of radical ion pairs, generated by photoindu ced electron transfer between prenyl and dimethylamiline linked by an oligopeptide bridge, was studied. From the size and characteristics of the magnetic field effect (MFE), it can be concluded that hydrogen bo nds within short peptide chains (here three glycine groups) or with a hydrogen-accepting solvent (acetone) do not seem to affect significant ly the chain dynamics.
