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.

在化学研究仪器和设施：多用户计划(CRIF：MU)的这一奖项下，加州大学圣地亚哥分校(UCSD)化学和生物化学系将获得一台具有低温能力的铜管CCD-X-射线衍射仪。它将用于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，7)海洋天然产物化学。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置在加州大学圣迭戈分校的X射线结晶学实验室。单晶X射线结晶学技术可以准确和精确地确定分子的全部三维结构，包括键的距离和角度，并提供关于分子相对于邻近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。
