In this collaborative project supported by the Chemical Structure, Dynamics and Mechanisms Program of the Division of Chemistry, Professor David N. Beratan of Duke University and Professor Igor Rubtsov of Tulane University willdevelop methods to control electron transfer reactions, and to develop approaches to manipulate the strength of the electronic communication between molecules that influences the rate of electron transfer. The Beratan group will employ quantum and statistical mechanical theories to design, analyze and interpret inelastic electron-transfer kinetics in molecules with bridge-localized vibrational modes. The goal is to develop interpretive and predictive descriptions of intramolecular inelastic electron-tunneling in a variety of molecules containing an electron donor, a rigid bridge, and an electron acceptor. The Rubtsov group at Tulane will develop ultrafast laser and multi-dimensional infrared spectroscopic methods to examine analogies between the double slit electron transmission experiment and the molecular electron-transfer problem. This work will a broad impact in developing intuition that may lead to applications in optical communication and solar energy harvesting. Professors Beratan and Rubtsov are promoting science education by providing summer research opportunities to economically disadvantaged and historically underrepresented groups. A new course cluster for first-year students is under development to examine the fundamental philosophical foundations of science.

在这个由化学系化学结构、动力学和机理项目支持的合作项目中，杜克大学的 David N. Beratan 教授和杜兰大学的 Igor Rubtsov 教授将开发控制电子转移反应的方法，并开发操纵电子转移反应的方法。影响电子转移速率的分子之间电子通讯的强度。贝拉坦小组将采用量子和统计力学理论来设计、分析和解释具有桥局域振动模式的分子中的非弹性电子转移动力学。目标是对包含电子供体、刚性桥和电子受体的各种分子中的分子内非弹性电子隧道进行解释和预测描述。 杜兰大学的鲁布佐夫小组将开发超快激光和多维红外光谱方法，以研究双缝电子传输实验和分子电子传输问题之间的类比。 这项工作将对培养直觉产生广泛影响，从而可能导致其在光通信和太阳能收集方面的应用。贝拉坦和鲁布佐夫教授通过向经济弱势群体和历史上代表性不足的群体提供夏季研究机会来促进科学教育。正在为一年级学生开发一个新的课程群，以研究科学的基本哲学基础。
