This grant from the Organic Dynamics Program supports the continuing work of Professor Closs at the University of Chicago. The results of this research will be of central importance in the areas of physical organic chemistry and biophysics. Intramolecular electron transfer and energy transfer processes will be studied in rigid molecules. Individual factors that govern these processes can then be determined. Dr. Closs proposes to effect intramolecular electron transfer by means of pulse radiolysis in rigid molecules. By this means the effects of free energy of reaction, distance over which electron transfer occurs, stereochemistry, solvent effects, and temperature effects may be analyzed. In these rigid molecules, it is expected that these effects may be analyzed by the examination of the structure of the molecule. In a similar manner, triplet energy transfer will be studied. Short-lived biradicals in solution will be examined by a newly developed EPR technique in a related study. //

有机动力学计划的这笔赠款支持 这是芝加哥大学克洛斯教授的继续研究。 这项研究的结果将是至关重要的， 物理有机化学和生物物理学领域。分子内 电子转移和能量转移过程将在 刚性分子控制这些过程的个体因素 然后可以确定。 Closs博士建议通过以下方式实现分子内电子转移： 刚性分子的脉冲辐解。通过这种方式 反应自由能的影响，电子 转移发生、立体化学、溶剂效应和温度 可以分析影响。在这些刚性分子中， 这些影响可以通过检查 分子的结构。同样，三重态能量 将研究转移。溶液中的短寿命双自由基将 在相关的研究中，用新开发的EPR技术进行检查。//
