MRI: Acquisition of a CCD-based Single Crystal X-Ray Diffractometer

加州大学化学系将获得一台单晶x射线衍射仪，该衍射仪具有最先进的电荷耦合探测器（CCD）和低温能力。主要用户将在以下研究领域使用新仪器：a)镧系元素和锕系元素的化学，b)非共价相互作用对金属介导转化的影响，c)小分子活化和催化的氧化还原活性配体，d)发明化学合成具有生物医学意义的复杂分子的新方法，e)立体选择碳-碳键形成的新方法。x射线衍射仪被广泛用于对反应产物进行快速和明确的表征，而用其他方法进行表征通常是困难的或不明确的。它们提供了分子的完整三维结构的精确测量，包括键的距离和角度，以及分子相对于邻近分子的空间排列。这些研究的结果有助于广泛的领域，包括无机，有机，有机金属，生物和材料化学。新仪器将成为当地学术和工业实验室的资源，并将为化学系的教育和推广计划做出重大贡献。

The Chemistry Department at the University of California will acquire a single crystal X-ray diffractometer with a state of the art charge coupled detector (CCD) and low temperature capability. The major users will make use of the new instrument in the following research areas: a) Chemistry of the lanthanide and actinide elements, b) Effects of non-covalent interactions on metal mediated transformations, c) Redox-active ligands for small molecule activation and catalysis, d) Invention of new methods for chemical synthesis of complex molecules of biomedical importance, e) New methods for stereoselective carbon-carbon bond-formation.X-ray diffractometers are widely used to allow prompt and definitive characterization of reaction products whose characterization by other means is often difficult or ambiguous. They provide accurate and precise measurements of the full three-dimensional structure of a molecule, including bond distances and angles, as well as the spatial arrangement of the molecule relative to the neighboring molecules. The results of these studies contribute to a broad range of areas, including inorganic, organic, organometallic, biological, and materials chemistry. The new instrument will be a resource for local academic and industrial laboratories and will contribute significantly to the Chemistry Department's educational and outreach programs.
