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.

化学研究工具和设施（CRIF）计划的奖项将使里奥皮德拉斯（Rio Piedras）波多黎各大学的化学系能够购买具有紫外线（UV），可见（VIS）和接近（NIR）能力的UV/VIS/NIR SpectroelectroChemistratus。 该设备将主要由初级教职员工拉斐尔·拉普蒂斯（Raphael Raptis）使用，其研究重点是研究金属/硫磺簇的系统结构重排，特别是在冷藏溶液和原位光谱表征中静电物种的稳定。 尽管各种金属簇在蛋白质的活性中心和矿物质中都存在，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 - chalcogenide簇构成了该领域的主要部分。 尽管在该领域进行了激烈的研究活动，但一般来说，金属 - chalcogenide簇和簇的合成仍然很大程度上依赖于偶然发现。 这些研究将扩大我们对这些重要金属簇的合成的理解。
