Purchase of Instrumentation for a Vibrational Sum Frequency Spectrometer

化学研究仪器和设施（CRIF）计划的这一奖项将使马里兰州大学的化学和生物化学系能够购买振动和频光谱仪的仪器。 该设备将主要由初级教员罗伯特A。步行者，他的研究重点是溶剂化动力学在固体：液体和液体：液体界面使用超快，非线性光学方法。 表面特定的振动和频产生已经成为一种宝贵的技术，研究分子结构和组成在所有类型的接口。 这项技术的普及源于它能够提供基于谱带位置和强度的分子构象的详细信息。 这些研究将扩展我们对凝聚相表面溶剂运动和弛豫的理解。

This award from the Chemistry Research Instrumentation and Facilities (CRIF) Program will enable the Department of Chemistry and Biochemistry at the University of Maryland in College Park to purchase instrumentation for a vibrational sum frequency spectrometer. This equipment will be used primarily by junior faculty member Robert A. Walker, whose research focuses on solvation dynamics at solid:liquid and liquid:liquid interfaces using ultrafast, nonlinear optical methods. Surface specific vibrational sum frequency generation has emerged as an invaluable technique for investigating molecular structure and composition at all types of interfaces. This technique's popularity stems from its ability to provide detailed information about molecular conformation based on band positions and intensities. These studies will extend our understanding of solvent motion and relaxation at condensed phase surfaces.
