Mechanistic and Exploratory Organic Photochemistry

该项目继续开展多样化的机械有机研究计划，涉及该领域的多个方面。 其中包括对激发态有机分子化学的研究，尚待确定替代产品的无辐射衰变或激发态超表面上的能量势垒是否控制了事件的进程。 用于探讨这些问题的方法包括量子力学、理论和实验化学。 另一种尝试涉及将反应分子嵌入尺寸有限且不规则的空腔中的情况。 然后构象限制改变了观察到的反应过程。 凭借该奖项，有机和高分子化学项目将继续支持威斯康星大学麦迪逊分校 Howard E. Zimmerman 教授的研究。 齐默尔曼教授的研究活动属于机械有机化学领域，该领域涉及在各种条件下密切观察化学反应，以便准确确定它们是如何发生的。 由于人们无法直接观察分子的反应，因此必须设计其他方法来推断这些事件。 齐默尔曼教授的实验室特别重视由光吸收和晶体内分子吸收引发的反应。

This project continues a variegated mechanistic organic research program that touches upon several aspects in the field. These include investigations of the chemistry of excited state organic molecules, where it remains to be determined if radiationless decay to alternative products or energy barriers on the excited state hypersurface govern the course of events. Methods used to probe these questions include quantum mechanical, theoretical, and experimental chemistry. A different endeavor involves the case where a reacting molecule is imbedded in a cavity of limited and irregular size. Conformational constraints then alter the otherwise observed course of the reaction. With this Award, the Organic and Macromolecular Chemistry Program continues support for the research of Professor Howard E. Zimmerman of the University of Wisconsin at Madison. Professor Zimmerman's research activities are in the area of mechanistic organic chemistry, which involves making close observations of chemical reactions under a variety of conditions in order to determine precisely how they occur. Since one cannot directly observe molecules as they react, one must devise other means of deducing these events. Particular emphasis in Professor Zimmerman's laboratories is given to reactions that are initiated by the absorption of light, and of molecules that are trapped within crystals.
