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 V. Rubtsov of Tulane University will develop methods to control electron transfer reactions. They will accomplish this goal by developing approaches to manipulate the strength of electronic communication within and between molecules; these electronic interactions influence the rates of electron transfer. The Beratan group will employ quantum and statistical mechanical theories to design, analyze and interpret inelastic electron-transfer kinetics in structures 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 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 have 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，大卫N。杜克大学的Beratan和杜兰大学的Igor V. Rubtsov教授将开发控制电子转移反应的方法。他们将通过开发控制分子内部和分子之间电子通信强度的方法来实现这一目标;这些电子相互作用影响电子转移的速率。Beratan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结构中的非弹性电子转移动力学。我们的目标是开发解释性和预测性的描述分子内的非弹性电子隧穿在各种分子中含有电子供体，桥，和电子受体。杜兰大学的Rubtsov小组将开发超快激光和多维红外光谱方法，以检验双缝电子传输实验和分子电子转移问题之间的相似性。这项工作将对开发可能导致光通信和太阳能收集应用的直觉产生广泛影响。Beratan教授和Rubtsov教授正在通过为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。
