Single crystal X-Ray diffraction is a leading technique for the determination of molecular and crystal structures and for obtaining the absolute configuration of molecules. This laboratory allows researchers to do small molecule single crystal structure determinations, where the metrical details of a molecule are ascertained (such as, bond lengths, bond angles, and conformation) along with the arrangement of the molecules within the solid state. Students with crystallographic experience can collect diffraction data and/or solve and refine their own structures. Otherwise, the complete structure analysis is done by the staff crystallographer. 

Equipment:

Nonius Kappa CCD diffractometer

A Nonius Kappa CCD diffractometer is equipped with a sealed tube generator with Mo radiation and an ApexII detector. An Oxford Cryosystems Cryostream Cooler provides low temperature data collection capability down to about 90 K using a cooled nitrogen gas stream. Access to the Cambridge Structural Database is available at the Ohio Supercomputer Center, or searches of this database can be done upon request of the staff crystallographer.
