With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at Georgetown University will acquire an X-ray powder diffractometer with area detector and variable temperature capability. This equipment will enhance research in a number of areas including the following: a) studies on liquid crystalline phases and the nature of the supramolecular structures in these systems; b) intermolecular interactions of and the supramolecular architecture of low molecular mass gelator materials within gel matrices; c) the relationship between growth of nanocrystalline solids in preferred orientations and resulting optical effects; and d) the identification of solid state materials via the determination of cell constants.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 a signifcant impact in materials sciences.
