With this award from the Chemistry Research Instrumentation and Facilities: Multi User program (CRIF:MU), the Department of Chemistry and Biochemistry at the University of California-San Diego (UCSD) will acquire a Cu-tube-based CCD-X-ray diffractometer with low temperature capabilities. It will be utilized in research projects including 1) charge transfer in inorganic mixed valence complexes, 2) patterned organic electron donor/acceptor nanostructures, 3) molecular nanomagnets, 4) supramolecular structures anti-infectives, 5) symmetry of hydrogen bonds, 6) novel fluorescent nucleoside analogues, and 7) marine natural products chemistry. The new Cu source X-ray diffractometer will be housed in the UCSD X-ray Crystallography Laboratory along with a Mo source diffractometer and an obsolete diffractometer. The technique of single-crystal X-ray crystallography allows accurate and precise determination of the full three dimensional structure of a molecule, including bond distances and angles, and it provides accurate information about the spatial arrangement of the molecule relative to the neighboring molecules. These studies will have an impact in a number of areas, especially synthetic chemistry.

凭借化学研究仪器和设施：多用户计划 (CRIF:MU) 的这一奖项，加州大学圣地亚哥分校 (UCSD) 化学与生物化学系将购买一台具有低温功能的基于铜管的 CCD-X 射线衍射仪。 它将用于包括1）无机混合价络合物中的电荷转移、2）图案化有机电子供体/受体纳米结构、3）分子纳米磁体、4）超分子结构抗感染、5）氢键对称性、6）新型荧光核苷类似物和7）海洋天然产物化学等研究项目。新的铜源 X 射线衍射仪将与一台钼源衍射仪和一台过时的衍射仪一起安装在 UCSD X 射线晶体学实验室。单晶 X 射线晶体学技术可以准确、精确地确定分子的完整三维结构，包括键距和角度，并提供有关分子相对于相邻分子的空间排列的准确信息。这些研究将在许多领域产生影响，特别是合成化学。
