Purchase of an X-Ray Diffractometer

根据化学研究仪器和设施：部门多用户仪器计划（CRIF:MU）授予的这份合同，麻省理工学院的Timothy M. Swager教授和Peter M. Mueller博士将获得一台单晶x射线衍射仪。该仪器将用于支持以下研究活动：1)若干含金属体系的氧化还原转化（Jonas Peters）；2)分子光催化体系的研究（Daniel Nocera）；3)多键配体含金属体系的表征（Christopher Cummins）；4)烯烃复分解和二氮还原新催化体系的发展（Richard Schrock）。该仪器还将在穆勒博士的教育推广活动中发挥重要作用。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邻近分子的空间排列的准确信息。这里描述的研究将影响许多领域，包括化学、催化和太阳能研究。使用该仪器的学生将获得尖端仪器的宝贵培训。

With this award from the Chemistry Research Instrumentation and Facilities: Departmental Multi-User Instrumentation program (CRIF:MU), Professor Timothy M. Swager and Dr. Peter M. Mueller from the Massachusetts Institute of Technology will acquire a single crystal X-ray diffractometer. The instrument will be used to support research activities such as: 1) redox transformations in a number of metal-containing systems (Jonas Peters); 2) study of molecular photocatalysis sytems (Daniel Nocera); 3) characterization of metal-containing systems with multiply-bonded ligands (Christopher Cummins); 4) the development of new catalysis systems for olefin metathesis and dinitrogen reduction (Richard Schrock). The instrument will also feature in the educational outreach activities of Dr. Mueller.An X-ray diffractometer allows accurate and precise measurements of the full three dimensional structure of a molecule, including bond distances and angles, and provides accurate information about the spatial arrangement of a molecule relative to neighboring molecules. The studies described here will impact a number of areas, including chemistry, catalysis and solar energy research. Students using the apparatus will receive valuable training with cutting-edge instrumentation.
