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）的化学和生物化学系将获得一台具有低温功能的Cu管CCD X射线衍射仪。 它将用于研究项目，包括1）无机混合价络合物中的电荷转移，2）图案化的有机电子供体/受体纳米结构，3）分子纳米磁体，4）超分子结构抗感染剂，5）氢键对称性，6）新型荧光核苷类似物，7）海洋天然产物化学。新的Cu源X射线衍射仪将与Mo源衍射仪和过时的衍射仪一起沿着在UCSD X射线晶体学实验室。单晶X射线晶体学技术允许准确和精确地确定分子的完整三维结构，包括键距和角度，并且它提供关于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。
