Chemistry of Weak Interactions in Organic Molecules

这笔来自有机动力学项目的拨款支持了克劳斯教授在芝加哥大学的继续工作。这项研究的结果将在物理、有机化学和生物物理学领域具有核心重要性。将研究刚性分子中的分子内电子转移和能量转移过程。然后，就可以确定支配这些过程的各个因素。克劳斯博士建议通过刚性分子中的脉冲辐解来实现分子内的电子转移。通过这种方法，可以分析反应自由能、电子转移距离、立体化学、溶剂效应和温度效应的影响。在这些刚性分子中，预计可以通过检查分子结构来分析这些影响。以类似的方式研究三重态的能量转移。在一项相关的研究中，将用一种新开发的EPR技术来检测溶液中的短寿命双自由基。//

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. //
