This award from the Chemistry Research Instrumentation and Facilities (CRIF) Program will enable the Department of Chemistry at the University of Puerto Rico in Rio Piedras to purchase UV/Vis/NIR spectroelectrochemistry apparatus with ultraviolet (UV), visible (Vis) and near infrared (NIR) capabilities. This equipment will be used primarily by junior faculty member Raphael Raptis, whose research focuses on the investigation of systematic structural rearrangements of metal/sulfur clusters, specifically the stabilization of electrogenerated species in chilled solution and in situ spectroscopic characterization. While various metal clusters occur in nature in the active centers of proteins and in minerals, a much larger number of cluster molecules have been synthesized in the laboratory in efforts to model proteins and catalyst surfaces. Metal-chalcogenide clusters make up a major part of this field. In spite of the intense research activity in this area, the synthesis of metal-chalcogenide clusters and clusters in general, has relied heavily on serendipitous discoveries. These studies will broaden our understanding of the synthesis of these important metal clusters.

化学研究仪器和设施（CRIF）计划的这一奖项将使位于Rio Piedras的波多黎各大学化学系能够购买具有紫外（UV），可见（维斯）和近红外（NIR）功能的UV/维斯/NIR光谱电化学仪器。 该设备将主要由初级教员拉斐尔·拉普蒂斯使用，他的研究重点是金属/硫簇的系统结构重排的研究，特别是冷冻溶液中电生成物种的稳定化和原位光谱表征。 虽然各种金属簇在自然界中存在于蛋白质和矿物质的活性中心，但在实验室中已经合成了大量的簇分子，以模拟蛋白质和催化剂表面。 金属硫族化合物团簇是这一领域的重要组成部分。 尽管在这一领域的研究活动非常激烈，但金属硫族化物簇合物和簇合物的合成在很大程度上依赖于偶然发现。 这些研究将拓宽我们对这些重要金属簇合物合成的理解。
