This award from the Chemistry Research Instrumentation and Facilities (CRIF) Program and the Major Research Instrumentation (MRI) Program will help the Department of Chemistry at Iowa State University acquire a CCD-based x-ray diffractometer. The equipment will enhance research in a number of areas which include programs in inorganic, organic, organometallic, solid state, and polymer chemistry. 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.
