With support from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at Pennsylvania State University will acquire a X-ray diffractometer with CCD detector and stereo microscope for small molecule diffractometry. This equipment will enhance research in a number of areas including the following: single crystal and fiber diffraction of phosphazene-based compounds and molecular inclusion clathrates; design and characterization of multi-dimensional covalent networks; novel methods of molecular recognition and the preparation of fluorescent chemical sensors; structural relationships between bioinorganic analogues and metalloprotein active sites; molecular recognition and artificial photosynthesis in lamellar and zeolitic solids; relating structural details to the mechanistic aspects of organometallic chemistry and homogeneous catalysis; structural characterization of complex natural products and their synthetic precursors; and structure-function relationships in enantioselective catalysts.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, including the preparation of more efficient catalysts, chemical sensors, and biochemistry.

在化学研究仪器和设施（CRIF）计划的支持下，宾夕法尼亚州立大学化学系将获得一台带有CCD检测器和体视显微镜的X射线衍射仪，用于小分子衍射。这一设备将加强若干领域的研究，包括：磷腈化合物和分子包合物的单晶和纤维衍射;多维共价网络的设计和表征;分子识别的新方法和荧光化学传感器的制备;生物无机类似物与金属蛋白活性部位之间的结构关系;层状和沸石固体中的分子识别和人工光合作用;将结构细节与有机金属化学和均相催化的机理方面联系起来;复杂天然产物及其合成前体的结构表征;以及对映选择性催化剂中的结构-功能关系。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，包括制备更有效的催化剂，化学传感器和生物化学。
