With a Major Research Instrumentation (MRI) award, the Department of Chemistry at Columbia University will acquire a single crystal X-ray diffractometer. This diffractometer is a CCD 3kW sealed tube system and includes a low temperature device. It will be employed in the following research areas: (i) analysis of retrodative bonding in metal borane compounds, (ii) structural characterization of compounds that mimic hydrodesulfurization catalysts, (iii) analysis of the diasteroselectivity in the formation of dioxetanes during the photooxygenation of enecarbamates, (iv) C-H bond functionalization in organic synthesis, (v) synthesis, self-assembly, and crystallography of organic electronic materials, and (vi) mechanisms of transition metal catalyzed ionic hydrogenation of organic substrates.The X-ray diffractometer allows the determination of accurate and precise bond distances and angles between atoms in a molecule. Upon analysis of the diffraction pattern, an investigator essentially maps out the three dimensional structure of a molecule, and the spatial arrangement of the molecule relative to the neighboring molecules. The composition of a solid material is fully described by analyzing the diffraction pattern. This equipment will be used in teaching and research. Undergraduate students will benefit from the instrument, and determine the structures of compounds that they are currently investigating in their research.

哥伦比亚大学化学系将获得一项重大研究仪器奖（MRI）奖，将获得单晶X射线衍射仪。该衍射仪是CCD 3KW密封管系统，包括低温装置。它将用于以下研究领域：（i）分析金属硼烷化合物中的翻新键合，（ii）模拟模仿氢化硫化催化剂的化合物的结构表征，（iii）对二核形成在二甲基化过程中的二核形成中的非对ini依性的分析（IIV有机电子材料的合成，自组装和晶体学以及（VI）过渡金属催化的有机基质的离子氢化机制。X射线衍射仪可以确定分子中原子之间的精确和精确的键距离和精确的键距离和角度。 通过分析衍射模式，研究者基本上映射了分子的三维结构，以及分子相对于相邻分子的空间排列。 通过分析衍射模式，充分描述了固体材料的组成。 该设备将用于教学和研究。本科生将从该工具中受益，并确定他们目前正在研究的化合物的结构。
