INVESTIGATION OF THE ONE-ELECTRON-TRANSFER STAGES IN COMPLEX ORGANIC-REACTIONS USING SPIN EFFECTS

The use of the spin chemistry techniques (chemically induced dynamic n uclear polarization and magnetic effects) made it possible to reveal a nd identify paramagnetic intermediates in several organic reactions of biologically important molecules. The photooxidation of the synthetic analogues of NADH, 1,4-dihydropyridines, by electron accepters and th e aerobic oxidation under the action of horseradish peroxidase, as wel l as the photoinduced interaction of all-trans-retinal with electron d onors and accepters, are examined.
