Solvent Dynamics in Reactivity and FDTD Simulation - IR Experiments of Liquids

本项目由芝加哥大学化学学部实验物理化学项目资助，由芝加哥大学Norbert Scherer教授进行两部分的研究：1)利用新开发的极化响应光谱（PORS）技术研究光驱动和反应性发色团耦合的溶剂动力学；2)进行结合全场模拟和时间分辨中红外（mid-IR）脉冲传播和泵浦探针研究的实验，以全面表征溶质与溶剂之间的相互作用。这两个部分都依赖于非线性光谱技术，他们的目标是研究影响溶质与其周围液体介质之间相互作用的基本问题。这些问题具有根本的重要性，研究结果为化学反应性和测量方法提供了新的实用见解。本研究将在学生和博士后研究助理的协助下进行。因此，他们将获得物理化学前沿领域之一的技能和培训，为深造或在科学/技术劳动力中就业做准备。

In this project, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Professor Norbert Scherer of the University of Chicago will pursue a research program consisting of two parts: 1) investigation of solvent dynamics coupled to photo-driven and reactive chromophores by means of the newly developed polarizability response spectroscopy (PORS) technique, and 2) conduct experiments that combine full-field simulations and time-resolved mid-infrared (mid-IR) pulse propagation and pump-probe studies to fully characterize the interaction between the solute and the solvent. Both parts rely on nonlinear spectroscopic techniques and their goal is to examine fundamental issues that affect the interaction between a solute and its surrounding liquid medium. These issues are of fundamental importance and the results of the investigations provide new practical insights into chemical reactivity as well as into the methodology of measurement. This research will be conducted with the assistance of students and postdoctoral research associates. They will thereby obtain skills and training in one of the forefront areas of physical chemistry in preparation for either advanced studies or employment in the scientific/technological workforce.
