The Small Molecule X-ray Crystallography Facility (a.k.a. CheXray) is a full service and user facility. We can provide you with all services related to the X-ray diffraction of single crystals and powders of small molecule compounds. Typically, X-ray diffraction is used to determine the solid-state molecular structure at the atomic level of crystalline samples, including absolute stereochemistry of chiral compounds. The facility currently houses state-of-the-art single crystal and powder X-ray diffractometers (see below for specific information about each instrument).
We also provide computational facilities for the analysis of data and are the Colleges distribution point for the Cambridge Structural Database. Training for new users on the single crystal diffractometers occurs through CHEM 208, which is offered in the Spring semester. If you have prior experience in operating a single crystal diffractometer and have taken the CHEM 208 equivalent course at another institution, the CHEM 208 requirement is waved. Users interested in operating the powder diffractometer are not required to take CHEM 208, either. See below for more information on becoming a facility user.
