Single Crystal X-ray Diffraction

Rigaku Oxford Diffraction SuperNovaSingle crystal diffraction is a powerful X-ray technique for structural solution of crystals typically of 20 - 200 microns in diameter. It provides key information on the symmetry and atom positions in these crystals. Usage spans from routine structural work on organic and metal-organic small molecules to highly detailed investigations of heavy metal oxides that can include twins, modulated structures or diffuse scattering.

The X-ray facility at Warwick is equipped with two single-crystal diffractometers. The Rigaku Oxford diffraction SuperNova is a state of the art Kappa geometry goniometer equipped with dual wavelength (Cu/Mo) microfocus X-ray source and an Atlas S2 CCD area detector which allows for extremely fast data collection of the entire Ewald sphere. In addition, it is equipped with an Oxford Cryosystems N-Helix cryo cooling system allowing for data collection down to 25K.


Rigaku Oxford Diffraction Gemini R

The Gemini R is a Kappa geometry goniometer equipped with dual wavelength (Cu/Mo) fine focus X-ray sources, graphite monocromators, Enhance optics and a Ruby CCD area detector, which allows for extremely fast data collection of the entire Ewald sphere. For low temperature experiments (80 K - 400 K) an Oxford Cryosystems Cobra is attached to the system.

On both systems, the CrysAlisPro software enables data collection, data intergration and absorption corrections to be made and is used in conjunction with refinement software such as Olex2 and ShelX.

Support for single-crystal diffraction is provided either by our resident Crystallographer, Dr Guy Clarkson, or by the Facility manager Dr David Walker.
