David N. Beratan of Duke University is supported by the Theoretical and Computational Chemistry Program to design, analyze and interpret inelastic electron-transfer kinetics in molecules with bridge-localized vibrational modes. He is developing 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. This work is in collaboration with the experimental group of Rubtsov at Tulane to examine analogies between the double slit electron transmission experiment and the molecular electron-transfer problem. The goal is to define new schemes to control electron transfer and to develop approaches to manipulate the strength of molecule-mediated electronic coupling. This work is having a broad impact in developing intuition that may lead to applications in optical communication and solar energy harvesting. The PI is 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.

杜克大学的David N. Beratan得到了理论和计算化学计划的支持，该计划在分子中设计，分析和解释具有桥梁位置振动模式的分子中的非弹性电子转移动力学。 他正在开发对包含电子供体，刚性桥和电子受体的各种分子中分子内非弹性电子隧道肺管的解释性和预测性描述。这项工作与图烷的Rubtsov实验组合作，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。 目的是定义新方案以控制电子传递，并开发方法来操纵分子介导的电子耦合的强度。 这项工作对开发直觉产生了广泛的影响，这可能导致光学通信和太阳能收集中的应用。 PI通过为经济弱势群体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。
