9357424 Scherer In this National Science Foundation Young Investigator project in the Experimental Physical Chemistry Program of the Chemistry Division, Norbert Scherer of the University of Pennsylvania will use time-domain spectroscopic techniques to study the role of solvents on chemical reaction dynamics in dense media and at interfaces. New solvent-selective optical and far-infrared (FIR) time-domain techniques will be developed to elucidate solvent involvement in chemical reactions on a molecular level in liquid, supercritical fluid, glass, and biological media. Scanning tunneling microscopy will be used in combination with femtosecond multiple-pulse techniques for the atomic specific detection of chemical processes at interfaces. %%% Through the results of experiments conducted under this research program Scherer will obtain a better understanding on a microscopic level of how molecules collide, exchange energy, and undergo chemical reaction in liquid and fluid media and at interfaces. The information and broader perspective obtained from these studies have the potential for directly observing and controlling chemical processes at the atomic level. This in turn has implications in such diverse areas as nanoscale fabrication of materials and destruction of toxic wastes. ***

9357424 Scherer 在这个国家科学基金会化学部实验物理化学计划的青年研究员项目中，宾夕法尼亚大学的 Norbert Scherer 将使用时域光谱技术来研究溶剂对致密介质和界面化学反应动力学的作用。 将开发新的溶剂选择性光学和远红外（FIR）时域技术，以阐明溶剂在液体、超临界流体、玻璃和生物介质中分子水平上参与化学反应的情况。 扫描隧道显微镜将与飞秒多脉冲技术结合使用，用于界面化学过程的原子特异性检测。 %%% 通过该研究计划下进行的实验结果，谢勒将在微观层面上更好地了解分子如何在液体和流体介质以及界面处碰撞、交换能量以及发生化学反应。 从这些研究中获得的信息和更广泛的视角有可能在原子水平上直接观察和控制化学过程。 这反过来又对材料的纳米级制造和有毒废物的销毁等不同领域产生影响。 ***
