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.

加州大学化学系将购置一台单晶X射线衍射仪，该仪器配备最先进的电荷耦合探测器（CCD）和低温性能。主要用户将在以下研究领域使用新仪器：a）镧系和锕系元素的化学，B）非共价相互作用对金属介导的转化的影响，c）用于小分子活化和催化的氧化还原活性配体，d）化学合成具有生物医学重要性的复杂分子的新方法的发明，e）立体选择性碳-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迅速和明确的表征，而用其他方法对反应产物的表征往往是困难的或不明确的。它们提供了分子完整三维结构的准确和精确测量，包括键距和键角，以及分子相对于相邻分子的空间排列。 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，并将大大有助于化学系的教育和推广计划。
