Acquisition of a CCD Single Crystal X-ray Diffraction System for a Partnership of Central New England Institutions

在主要研究仪器（MRI）计划的支持下，基恩州立学院化学系将获得一台具有CCD检测器和低温能力的单晶X射线衍射仪。六所私立文科本科学校（克拉克大学、达特茅斯学院、米德尔伯里学院、圣安瑟伦学院、威廉姆斯学院和伍斯特理工学院）的教师也将有机会使用衍射仪。 新仪器将加强14个学院的基本理解，研究和教学工作，研究计划围绕几个领域，包括使用无机和有机金属化合物的催化，生物活性化合物的天然产物合成，2D和3D分子框架中的主客体行为/交换，分子磁性材料的合成，以及分子晶体中的固态反应性和多态性。X射线衍射仪可以准确和精确地测量分子的完整三维结构，包括键距和键角，并且它提供了关于分子相对于相邻分子的空间排列的精确信息。这些研究将在许多领域产生影响，特别是材料化学和生物化学。

With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at Keene State College will acquire a single-crystal X-ray diffractometer with CCD detector and low temperature capability. Faculty at six private liberal arts undergraduate schools (Clark University, Dartmouth College, Middlebury College, St. Anselm College, Williams College and Worcester Polytechnic Institute) will also have access to the diffractometer. The new instrument will enhance the basic understanding, research and teaching efforts of fourteen faculty with investigative schemes centered around several areas including catalysis using inorganic and organometallic compounds, natural product synthesis of biologically active compounds, host-guest behavior/exchange in 2D and 3D molecular frameworks, synthesis of molecular magnetic materials, and solid-state reactivity and polymorphism in molecular crystals.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 and biochemistry.
