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.

这份来自化学研究仪器和设施（CRIF）项目的合同将使马里兰大学化学和生物化学系能够为振动和频率光谱仪购买仪器。该设备将主要由初级教员Robert A. Walker使用，他的研究重点是使用超快非线性光学方法研究固液和液液界面的溶剂化动力学。表面比振动和频率产生已经成为研究所有类型界面上分子结构和组成的宝贵技术。这项技术的流行源于它能够提供基于能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溶剂在凝聚相表面的运动和弛豫的理解。
