The goal of the proposed research is to gain a fundamental understanding of the factors governing the energetics and efficiency of photochemical energy conversion in both natural and artificial photosynthetic systems. The phenomenon of electron-spin polarization, which is associated with the early events that occur following the absorption of light, provides an observable that gives very detailed information on a molecular and electronic level. Our suite of modern time-resolved electron paramagnetic resonance (EPR) instruments allows us to use the spin polarization of light-induced paramagnetic species to study these events in detail and

拟议的研究的目标是获得一个基本的了解的因素，在自然和人工光合系统的光化学能量转换的能量和效率。电子自旋极化现象与光吸收后发生的早期事件有关，它提供了一个在分子和电子水平上提供非常详细信息的可观察性。我们的现代时间分辨电子顺磁共振（EPR）仪器套件使我们能够使用光诱导顺磁物质的自旋极化来详细研究这些事件，
