U. Werner et al., ELECTRON-TRANSFER AND MAGNETIC-FIELD EFFECTS IN COVALENTLY-LINKED PYRENYL OLIGOPEPTIDE DIMETHYLANILINE COMPOUNDS, Journal of photochemistry and photobiology. A, Chemistry, 85(1-2), 1995, pp. 77-83
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.
