The goal of the proposed research is to gain a fundamental understanding of the factors governing the efficiency of solar energy conversion in natural and artificial photosynthetic systems. Our suite of modern time resolved electron paramagnetic resonance (EPR) instruments allows us to measure the electron spin polarization associated with the energy conversion and to use it to study the initial steps of this process in detail. Our close collaborations with groups in the US, Germany, Russia and Japan give us access to a wide range of complementary spectroscopic, theoretical, biochemical and molecular biology techniques. Using this broad array of methods, we are putting together an exquisitely detailed picture of the energetics, kinetics and dynamics of these vitally important systems. We are now using this knowledge to aid in the design and characterization of artificial mimics of the natural systems.

拟议研究的目标是获得对自然和人工光合系统中控制太阳能转换效率的因素的基本理解。我们的一套现代时间分辨电子顺磁共振（EPR）仪器使我们能够测量与能量转换相关的电子自旋极化，并使用它来详细研究这一过程的初始步骤。我们与美国，德国，俄罗斯和日本的团队密切合作，使我们能够获得广泛的互补光谱，理论，生化和分子生物学技术。使用这些广泛的方法，我们将这些至关重要的系统的能量学、动力学和动力学的精细细节组合在一起。我们现在正在利用这些知识来帮助设计和表征自然系统的人工模拟。
