Abstract

Key species: Radical pairs generated by photo-induced electron transfer in synthesized DNA are characterized by time-resolved electron paramagnetic resonance (EPR) spectroscopy. Assuming the B-form for DNA, the observed polarization patterns are reproduced taking into account the spin-correlated radical pair mechanism of the electron spin polarization (see figure) and the charge recombination dynamics.
