本研究项目在分析和表面化学计划的支持下，探索了铂单晶表面吸附的光裂解和光反应的动力学。超高压表面科学技术以及激光光谱方法将用于提供关于固体表面上的光诱导反应过程的详细信息。在这些表面取向的光反应中探测到的受限的几何和能量范围可能提供对化学反应动力学的一般理解，并将挑战我们目前对固体表面反应过程的理解。%由光吸收引发的吸附分子之间的反应将被用作化学反应动力学的一般探针。从这些研究中获得的洞察力将增加我们对表面反应特别是分子反应化学的理解。此外，这可能有助于理解重要的表面催化反应过程。

This research project, supported by the Analytical and Surface Chemistry Program, explores the dynamics of adsorbate photofragmentation and photoreaction on platinum single crystal surfaces. Both UHV surface science techniques as well as laser spectroscopic methods will be used to provide detailed information about the process of photoinduced reactions on solid surfaces. The restricted geometry and energy range probed in these surface aligned photoreactions may provide a general understanding of chemical reaction dynamics, and will challenge our present understanding of reaction processes at solid surfaces. %%% The reaction between adsorbed molecules initiated by the absorption of light will be used as a general probe of the dynamics of chemical reactions. The insight gained from these studies will increase our understanding of surface reactions in particular, and molecular reaction chemistry in general. In addition, there may be benefits to the understanding of important surface catalyzed reaction processes.
