在这项工作中，我们建议扩大范围的单分子光谱的自旋化学调查的单自由基对。提出了一个一致的理论，单分子光谱上的单个自由基对，它允许一个表明，聚束现象的影响，单重态三重态相互转换的自由基对，这是反过来，受本地和外部磁场。这种实验的可行性与单黄素腺嘌呤二核苷酸，FAD，分子的详细研究。我们的结论是，磁场对单个FAD分子的影响的观察是可行的，但在实验上具有挑战性的综合荧光强度和荧光事件统计的测量。
In this work, we propose to extend the scope of single-molecule spectroscopy to spin chemistry investigations of single radical pairs. A consistent theory of single-molecule spectroscopy on single radical pairs is proposed, which allows one to show that bunching phenomena are affected by singlet–triplet interconversion in radical pairs, which is, in turn, affected by local and external magnetic fields. A detailed study on the feasibility of such experiments with single flavin adenine dinucleotide, FAD, molecules is presented. We conclude that the observation of magnetic field effects on single FAD molecules is feasible but experimentally challenging for measurements on integrated fluorescence intensity and fluorescence event statistics.
