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.

格雷厄姆·R博士弗莱明的加州大学伯克利分校是资助他的研究光学研究的凝聚相动力学的赠款在物理化学计划的化学部。 他将开发和应用新的超快激光光谱方法的复杂凝聚相系统的动力学。 具体而言，他将开发外差检测，二维拉曼光谱，双色共振光子回波光谱的液体和玻璃动力学的研究，和多色分子复合物的研究，分别。 本科生，研究生和博士后学生将接受实验设计，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。持续时间为万亿分之几秒的超短激光脉冲将用于跟踪化学反应过程中分子的运动，并研究在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自然光的捕光功能。植物的光合系统 这项研究的长期目标是揭示基于太阳能的可再生能源的设计原则，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。
