The Diffracto-Cam
The Chemistry Department X-ray Crystallography Lab is located on the third floor of the Chevron Science Center. We have a Bruker Smart Apex CCD diffractometer (sealed-tube Mo radiation, pictured above) which is controlled via Bruker Smart software. We are equipped for low-temperature data collection down to 90K.
We use primarily the Bruker SHELXTL package (which we used to produce the pictures on this page and in our gallery) for the solution, refinement and visualization of X-ray structures. Other programs we have found useful include Platon from Dr. A.L. Spek, Babel from U. of AZ, and the Cambridge Structural Database.
We use X-ray diffraction to determine the three-dimensional structure of organic and inorganic molecules which have been created in the various synthetic research groups here in the University of Pittsburgh Chemistry Department. We also collaborate with chemists outside the university. A Gallery of some favorite structures can be found here. Click here for a tutorial on X-ray diffraction. Click here for a bio of Wilhelm Conrad Röntgen (discoverer of X-rays). Röntgen won one of several Nobel Prizes for research with X-rays.
