Photoinduced electron transfer generates radical pairs which recombine with 10(-9)10(-8)s by electron back-transfer to either singlet or triplet products. The product distribution determined by the spin motion of the unpaired electrons in the radical pairs is affected by external magnetic fields. The analysis of the magnetic field effect furnishes new information about electron transfer processes. Light-induced electron transfer in polar solvents and in the bacterial photosynthetic reaction center are discussed as examples.
光诱导电子转移产生自由基对，这些自由基对通过电子反向转移在10⁻⁹至10⁻⁸秒内与单重态或三重态产物重新结合。由自由基对中未配对电子的自旋运动决定的产物分布会受到外部磁场的影响。对磁场效应的分析提供了有关电子转移过程的新信息。作为示例，讨论了极性溶剂和细菌光合反应中心中的光诱导电子转移。
