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.
