Optical Studies of Condensed Phase Dynamics

加州大学伯克利分校的格雷厄姆·R·弗莱明博士是由化学部物理化学项目的一笔赠款资助他在凝聚相动力学光学研究方面的研究。他将开发和应用新的超快激光光谱方法来研究复杂凝聚相系统的动力学。具体地说，他将开发外差探测、二维拉曼光谱和双色共振光子回声光谱，分别用于液体和玻璃动力学的研究，以及多发色分子络合物的研究。本科生、研究生和博士后将接受实验设计、测量和理论分析方面的培训和教育。学生将准备领导主要研究型大学、国家实验室和私营企业的独立研究项目。持续时间为万亿分之一秒的超短激光脉冲将被用于跟踪化学反应中分子的运动，并研究纳米设备中涉及的太阳能收集和转移过程，该设备旨在模拟和扩展植物自然光合作用系统的光收集功能。这项研究的长期目标是揭示基于太阳能的可再生能源所必需的设计原则，为化学过程的研究和优化提供新的分析方法，并培养下一代美国科学家。

Dr. Graham R. Fleming of the University of California at Berkeley is funded for his research on optical studies of condensed phase dynamics by a grant in the Physical Chemistry program of the Chemistry Division. He will develop and apply new ultrafast laser spectroscopic methods to the dynamics of complex condensed phase systems. Specifically, he will develop heterodyne-detected, two-dimensional Raman spectroscopy, and two-color resonant photon echo spectroscopy for the study of liquid and glass dynamics, and the study of multichromophoric molecular complexes, respectively. Undergraduate, graduate, and postdoctoral students will receive training and education in experimental design, measurement, and theoretical analysis. Students will be prepared to lead independent research programs at major research universities, National Laboratories, and private industry.Exceedingly short pulses of laser light with duration of a few thousandths of a trillionth of a second will be used to follow the motions of molecules during chemical reactions, and to study the processes involved in the collection and transfer of solar energy in nanoscale devices designed to mimic and extend the light harvesting function of the natural photosynthetic system of plants. The long range goals of this research are to reveal the design principles necessary for renewable energy sources based on solar energy, to provide new analytical methods for the study and optimization of chemical processes, and to train the next generation of U.S. scientists.
