Purchase of an X-ray Diffractometer

化学研究仪器和设施计划（CRIF）和多学科活动办公室（OMA）的这一奖项将帮助普林斯顿大学化学系获得配备CCD探测器的X射线衍射仪。这些设备将加强若干领域的研究，包括：（1）具有不寻常的电子和磁性的新氧化物和硫属化物，（2）与细胞色素P450的化学有关的氧化催化，以及模型磷脂中的矢量分子自组装，（3）活性中间体，（4）增加极性分子吸收的化合物的设计，（5）合成无机化学;（6）芳香族分子中不寻常的结构和键合。 X射线衍射仪用于精确测量分子的完整三维结构。所获得的信息给出了给定分子的所有键距和键角的精确值，并且它给出了关于该分子相对于相邻分子的空间排列的准确信息。

This award from the Chemistry Research Instrumentation and Facilities Program (CRIF) and the Office of Multidisciplinary Activities (OMA) will help the Department of Chemistry at Princeton University acquire a x-ray diffractometer equipped with a CCD detector. The equipment will enhance research in a number of areas including the following: (1) new oxides and chalcogenides with unusual electronic and magnetic properties, (2) oxidation catalysis related to the chemistry of cytochrome P450, and vectorial molecular self-assembly in model phospholipid, (3) reactive intermediates, (4) design of compounds which increase the absorption of polar molecules, (5) synthetic inorganic chemistry, and (6) unusual structure and bonding in aromatic molecules. The X-ray diffractometer is used to make accurate and precise measurements of the full three dimensional structure of a molecule. The information obtained gives the precise values of all the bond distances and bond angles of a given molecule and it gives accurate information about the spatial arrangement of the molecule relative to the neighboring molecules.
