With this award the Organic and Macromolecular Chemistry Program supports the work of Dr. Stephen F. Nelsen at the University of Wisconsin at Madison. The research aims to probe the details of electron transfer (ET) reactions in organic intervalence compounds - compounds with two charged units connected by a bridge of connected atoms where the only difference between the two units is the amount of charge, and also between molecules of known oxidation potential. Intervalence compounds have no driving force (the energy is the same irrespective of which unit has the higher charge), and provide a good test of theoretical models. ET reactions are very important in both chemistry and biology, and are found for example in photosynthesis and respiration.Intervalence compounds show a charge transfer band arising from a vertical ET transition induced by absorption of a visible photon. Compounds with organic charge-bearing units that are stable, and have high internal reorganization energies, will be synthesized and studied in order to measure rate constants for thermal ET and to compare the experimental results with theoretical models.

有了这个奖项，有机和高分子化学计划支持博士斯蒂芬F。Nelsen在麦迪逊的威斯康星州大学。 该研究旨在探索有机化合物中电子转移（ET）反应的细节-具有两个带电单元的化合物通过连接原子的桥连接，其中两个单元之间的唯一差异是电荷量，以及已知氧化电位的分子之间的差异。 间隔化合物没有驱动力（能量是相同的，不管哪个单元具有更高的电荷），并提供了一个很好的测试理论模型。 ET反应在化学和生物学中都非常重要，例如在光合作用和呼吸作用中发现。价间化合物显示出由吸收可见光子引起的垂直ET跃迁产生的电荷转移带。 将合成和研究具有稳定的有机电荷承载单元的化合物，并具有高的内部重组能，以测量热ET的速率常数，并将实验结果与理论模型进行比较。
