Purchase of a CCD Area Detector-Equipped Single Crystal X-ray Diffractometer

这份来自化学研究仪器和设施项目（CRIF）以及学术研究和基础设施项目（ARI）的合同将帮助阿拉巴马塔斯卡卢萨大学化学系获得一台CCD x射线衍射仪。该设备将加强以下领域的研究：(1)有机供体-受体固体和高自旋多自由基离子的结构研究；(2)单分子整流剂和有机导体的表征；(3)多自由基离子和其他萃取剂与金属离子相互作用的研究；(4)新型超强酸催化剂的研究；(5)多核铬-羧酸盐组装体的研究。x射线衍射仪用于对分子的完整三维结构进行精确的测量。所获得的信息给出了给定分子的所有键距和键角的精确值，并给出了分子相对于邻近分子的空间排列的准确信息。

9626144 Kispert University of Alabama Tuscaloosa This award from the Chemistry Research Instrumentation and Facilities Program (CRIF) and the Academic Research and Infrastructure (ARI) Program will assist the Department of Chemistry at the University of Alabama Tuscaloosa acquire a CCD X-RAY Diffractometer. This equipment will enhance research in a number of areas including the following: (1) structural investigation of organic donor-acceptor solids and high-spin polyradical ions (2) characterization of unimolecular rectifiers and organic conductors (3) study of polyradical ions and other extractant interactions with metal ions (4) investigation of novel superacid catalysts, and (5) study of mutinuclear chromium-carboxylate assemblies. The X-ray diffractometer is used to make accurate and precise measurements of the full three dimensional structure of a molecule. The information obtained gives the precise values of all the bond distances and bond angles of a given molecule and it gives accurate information about the spatial arrangement of the molecule relative to the neighboring molecules.
