9414271 Roth Rutgers University New knowledge about the structures and reactions of organic radical cations will be provided as well as new insights into light-induced electron transfer reactions. A variety of radical cations will be generated in a range of media, including fluid solutions, frozen glasses, and solid supports (e.g., zeolites) by methods that include photo-induced electron transfer, chemical oxidation, and radiolysis. Their structures will be characterized by spectroscopic methods which include optical spectroscopy, ESR, and CIDNP. The experiments will supplemented by ab initio molecular orbital calculations. This grant from the Organic Dynamics Program supports the continuing work of Professor Heinz D. Roth at Rutgers University. Radical cations that will be studied by Professor Roth are reactive molecules that carry one unit of positive charge and one electron that is not paired with another electron. Radical cations may under go reaction either at the unpaired electron site or at the site of positive charge. These reactions as well as others will be addressed in this research. In addition, the structures of radical cations will be determined by modern spectroscopic techniques in various environments. Theoretical calculations will supplement the experiments.

9414271 Roth Rutgers University 将提供有关有机自由基阳离子的结构和反应的新知识以及对光诱导电子转移反应的新见解。通过光诱导电子转移、化学氧化和辐射解等方法，将在一系列介质中产生各种自由基阳离子，包括流体溶液、冷冻玻璃和固体载体（例如沸石）。它们的结构将通过光谱方法进行表征，包括光谱法、ESR 和 CIDNP。实验将辅以从头算分子轨道计算。 有机动力学计划的这笔赠款支持罗格斯大学 Heinz D. Roth 教授的持续工作。罗斯教授将研究的自由基阳离子是带有一个正电荷单位和一个不与另一个电子配对的电子的反应性分子。自由基阳离子可以在不成对电子位点或正电荷位点发生反应。这些反应以及其他反应将在本研究中得到解决。此外，自由基阳离子的结构将通过现代光谱技术在各种环境下测定。理论计算将补充实验。
