This short review reports the surprising phenomenon of nuclear hyperpolarization occurring in chemical reactions, which is called CIDNP (chemically induced dynamic nuclear polarization) or photo-CIDNP if the chemical reaction is light-driven. The phenomenon occurs in both liquid and solid-state, and electron transfer systems, often carrying flavins as electron acceptors, are involved. Here, we explain the physical and chemical properties of flavins, their occurrence in spin-correlated radical pairs (SCRP) and the possible involvement of flavin-carrying SCRPs in animal magneto-reception at earth’s magnetic field.

黄素蛋白的自旋动力学

这篇简短的综述报告了化学反应中发生的令人惊讶的核超极化现象，如果化学反应是光驱动的，则称为 CIDNP（化学诱导动态核极化）或光 CIDNP。这种现象发生在液态和固态中，并且涉及通常携带黄素作为电子受体的电子转移系统。在这里，我们解释了黄素的物理和化学性质、它们在自旋相关自由基对 (SCRP) 中的出现以及携带黄素的 SCRP 可能参与地球磁场中的动物磁接收。
