Optical Studies of Condensed Phase Dynamics

加州大学伯克利分校的格雷厄姆·r·弗莱明博士在凝聚态动力学的光学研究方面获得了化学学部物理化学项目的资助。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。具体来说，他将开发外差检测、二维拉曼光谱和双色共振光子回波光谱，分别用于研究液体和玻璃动力学，以及研究多色分子复合物。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。学生将准备在主要的研究型大学、国家实验室和私营企业领导独立的研究项目。持续时间仅为万亿分之一秒的极短激光脉冲将用于跟踪化学反应过程中的分子运动，并用于研究纳米级设备中收集和转移太阳能的过程，这些设备旨在模仿和扩展植物自然光合系统的光收集功能。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.
