项目摘要

In this award, funded by the Experimental Physical Chemistry Program of the Division of Chemistry, Professor Roseanne Sension of the University of Michigan along with her post-doctoral fellows and graduate students plan to perform experiments aimed at influencing both condensed phase molecular dynamics & chemical reactivity along with the identification of effective pulse shapes through learning algorithm approaches. The overarching goal of these studies is focused on linking sophisticated observation of reaction dynamics with the ability to control chemical reactions either directly or indirectly. Five specific systems are proposed for study: 1) Control of Reactive Excited State Branching in Cis-Stilbene, 2) Control of Photodissociation Channels in Solution Phase, 3) Control of Excited State Branching in Pyrimidine DNA Bases, 4) 1,3-Cyclohexadiene Ring-Opening Reaction, and 5) The Pro-Vitamin D Ring-Opening Reaction. Techniques such as ultraviolet (UV) pulse shaping, excited state measurements, theoretical calculations, and multi-photon laser excitation will be employed.The nature of this work is at the forefront of modern optical techniques and exposes students to state-of-the-art research in chemical physics and optical physics. Students and other research associates will have access to advanced laser pulse generation techniques. Integration with education will include augmenting the computational chemistry curriculum to include modeling and simulation of the chemical dynamics observed in ultrafast laser experiments.

在该奖项中，由化学系实验性物理化学计划资助，密歇根大学的Roseanne Sension以及她的博士后研究员和研究生计划进行实验，旨在执行旨在影响凝聚相分子动力学和化学反应性的实验，以及通过学习ALGORITHM方法识别有效的脉搏塑造。这些研究的总体目标集中在将反应动力学的复杂观察与直接或间接控制化学反应的能力联系在一起。提出了五个特定系统以进行研究：1）控制顺式 - 静脉中的反应性激发态分支，2）控制溶液阶段的光解离通道，3）控制嘧啶DNA碱基中激发态分支的控制，4）1,3-环己二烯烯环循环反应反应，以及5）Pro-Vitamin d d d dnemin d dnamin d d dnemin d环环反应。将采用紫外线（UV）脉冲塑形，激发状态测量，理论计算和多光子激光兴奋等技术。这项工作的性质是现代光学技术的最前沿，并使学生对化学物理学和光学物理学的最新研究暴露于最新的研究。学生和其他研究伙伴将可以使用高级激光脉冲产生技术。与教育的融合将包括增加计算化学课程，以包括对超快激光实验中观察到的化学动力学的建模和模拟。
