The Chemistry Department at Eastern Illinois University will acquire a single crystal X-ray diffractometer with a charge coupled detector (CCD) and low temperature capability. The instrumentation will support the research programs of faculty at EIU, and programs at Manhattan College, Oakland University, St. Joseph's University, University of Central Missouri, University of North Carolina at Wilmington, University of Tulsa, and Western Illinois University. The primary research that would be supported by the proposed diffractometer falls into four broad categories: i) constrained molecular frameworks, ii) functional materials, iii) supramolecular assemblies and iv) the investigation of synthetic processes. X-ray diffractometers are widely used to provide characterization of reaction products and materials. Often characterization by other means is difficult or ambiguous. X-ray diffraction patterns provide accurate measurements of the three-dimensional structure of a molecule, including bond distances and angles, as well as the spatial arrangement of the molecule relative to the neighboring molecules. The results of these studies contribute to a broad range of areas, including inorganic, organic, organometallic, biological, and materials chemistry. Eastern Illinois University plans to establish an integrative applied crystallography center open to students and faculty in the greater academic community of small colleges and universities that are supporting undergraduate research activities.

东伊利诺伊大学化学系将获得一台具有电荷耦合探测器(CCD)和低温能力的单晶X射线衍射仪。该仪器将支持经济学人智库教职员工的研究项目，以及曼哈顿学院、奥克兰大学、圣约瑟夫大学、中央密苏里大学、北卡罗来纳大学威尔明顿分校、塔尔萨大学和西伊利诺伊大学的项目。建议的衍射仪将支持的主要研究分为四大类：i)受限分子骨架，ii)功能材料，iii)超分子组装和iv)合成过程的研究。X射线衍射仪被广泛用于对反应产物和材料进行表征。通过其他方式进行描述往往是困难的或模棱两可的。X射线衍射图提供了对分子三维结构的准确测量，包括键距离和键角，以及分子相对于邻近分子的空间排列。这些研究的结果有助于广泛的领域，包括无机、有机、有机金属、生物和材料化学。东伊利诺伊大学计划建立一个综合性的应用结晶学中心，向支持本科生研究活动的小型学院和大学的更大学术社区的学生和教职员工开放。
