Here, we present a protocol for the determination of cage-escape yields following excited-state electron transfer between a photosensitizer and a quencher. We describe steps for determining changes in molar absorption coefficient of the different oxidation states via photolysis experiments and the percentage of reacted species via steady-state or time-resolved spectroscopy. We then detail measurement of the amount of formed product via nanosecond transient absorption spectroscopy. For complete details on the use and execution of this protocol, please refer to Ripak et al. (2023)..
在此，我们展示了一种用于测定光敏剂与猝灭剂之间激发态电子转移后笼逃逸产率的方案。我们描述了通过光解实验确定不同氧化态摩尔吸收系数变化的步骤，以及通过稳态或时间分辨光谱法确定反应物种百分比的步骤。然后，我们详细介绍了通过纳秒瞬态吸收光谱法测量生成产物量的方法。有关此方案的使用和执行的完整详细信息，请参考里帕克等人（2023年）的文献。
