RUI: Upgrade of a P4 Diffractometer to CCD Capability

在主要研究仪器（MRI）计划的支持下，西南德克萨斯州立大学化学系将为其P4衍射仪增加CCD功能，这将允许小分子衍射。这一设备将加强若干领域的研究，包括：a）定点诱变; B）基于双桥连杯[6]芳烃的催化剂和传感器的组合合成;和c）多面体硼烷阴离子研究。X射线衍射仪允许精确和精确地测量分子的全部三维结构，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。

With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at Southwest Texas State University will add CCD capability to their P4 diffractometer, which will allow small molecule diffractometry. This equipment will enhance research in a number of areas including the following: a) site-directed mutagenesis; b) combinatorial synthesis of catalysts and sensors based on bis-bridged calix[6]arenes; and c) polyhedral borane anion investigations.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.
