This award from the Chemistry Research Instrumentation and Facilities Program will assist the Department of Chemistry at University of California at Berkeley in the purchase of a new X-ray diffractometer equipped with a high-resolution, high-sensitivity area detector with associated computers. This new instrumentation will enhance greatly research in a number of areas including the following: 1) Stereognostic Coordination Chemistry 2) Lanthanide and Actinide Coordination Chemistry 3) Coordination Chemistry of Biological Iron Transport 4) Metal Complexes with Te and Se-Containing Ligands 5) Transition Metal-Silicon Chemistry 6) Synthesis and Study of New Electroactive Polymers 7) Single-Source Precursors to Elaborate Solid-State Structures 8) Structures of the Oxide Superconductors and Related Materials and 9) Conformationally Constrained and Templated Peptides. 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.

这份来自化学研究仪器和设施项目的合同将帮助加州大学伯克利分校化学系购买一台新的x射线衍射仪，该衍射仪配备了高分辨率、高灵敏度的区域探测器和相关的计算机。这种新仪器将极大地加强在许多领域的研究，包括：1)立体识别配位化学2)镧系元素和锕系元素配位化学3)生物铁转运的配位化学4)含Te和se配体的金属配合物5)过渡金属-硅化学6)新型电活性聚合物的合成与研究7)制备固态结构的单源前体8)氧化物超导体及相关材料的结构9)构象约束和模板化肽。​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。
