Several flavoproteins convert light into transient nuclear hyperpolarization via spin evolution of spin-correlated radical pairs. This phenomenon is called photochemically induced dynamic nuclear polarization (photo-CIDNP). Photo-CIDNP is observed in NMR spectroscopy as non-Boltzmann nuclear magnetization allowing for a substantial increase in signal intensity. However, the structural preconditions initiating photo-CIDNP and its mechanism are far from being understood. Here, we aim for exploring the underlying principles of photo-CIDNP. Our results will help to induce, tailor, and control photo-CIDNP in molecular systems.
