Time‐resolved EPR spectroscopy was used to follow the primary triplet electron‐transfer reaction of model compound 1 and its trans isomer in the 100 ns to several 10 μs range. This method allows not only the unequivocal identification of transient radical pairs but also the systematic study of their interactions, which govern the recombination dynamics in photosynthesis.
