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.

在这个合作项目中，化学结构，动力学和机制计划的支持，杜克大学杜克大学的David N. Beratan教授以及杜兰大学Will University的Igor Rubtsov教授威尔大学Will Developpepent方法控制电子转移反应，并开发方法来操纵影响电子传输速率的分子之间的电子通信强度。 BERATAN组将采用量子和统计机械理论来设计，分析和解释具有桥梁 - 定位振动模式的分子中的非弹性电子转移动力学。目的是在包含电子供体，刚性桥和电子受体的各种分子中开发分子内非弹性电子接触的解释性和预测性描述。 Tulane的Rubtsov组将开发超快速激光和多维红外光谱方法，以检查双缝电子传输实验与分子电子转移问题之间的类比。 这项工作将在开发直觉上产生广泛的影响，这可能导致光学通信和太阳能收集中的应用。 Beratan和Rubtsov教授通过为经济不利的且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。一个针对一年级学生的新课程集群正在开发中，以研究科学的基本哲学基础。
