With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at Vassar College will acquire a single-crystal X-ray diffractometer with CCD detector. This instrument will facilitate research in a number of areas: (1) the investigation of paramagnetic and air-sensitive coordination compounds; (2) the structural investigation of microcrystalline extended structure network materials; (3) examination of twinned derivatives of giant fullerenes; (4) the study of hydrogen bonding structures exhibited by organic anion receptors and synthetic peptide mimics; and (5) the analysis of biologically active small molecule and natural product compounds. The X-ray diffractometer allows accurate and precise measurements 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 materials chemistry, biochemistry and medicinal chemistry.

在主要研究仪器（MRI）计划的支持下，瓦萨学院化学系将获得一台带有CCD检测器的单晶X射线衍射仪。这一仪器将促进若干领域的研究：（1）顺磁性和空气敏感性配位化合物的研究;（2）微晶扩展结构网络材料的结构研究;（3）巨型富勒烯的孪生衍生物的研究;（4）有机阴离子受体和合成肽模拟物显示的氢键结构的研究;（5）分子间相互作用的研究。（5）生物活性小分子和天然产物化合物的分析。X射线衍射仪可以精确测量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，特别是材料化学，生物化学和药物化学。
