Molecular Structure Analysis: Single-Crystal X-ray Diffraction

Single-crystal X-ray diffraction is a powerful method in chemistry and materials science that makes it possible to determine the three-dimensional structure of molecules in crystals. In a typical experiment, a monocrystalline specimen is irradiated using an X-ray source and the resulting diffraction pattern can be analyzed to determine structural parameters such as  atomic positions, and interatomic distances and angles.

We offer diffraction measurements for a variety of crystalline samples and are particularly well equipped to measure diffraction patterns from weakly-diffracting crystals. More Information regarding our instrumentation and service below.

Other tools to consider: NMR Spectroscopy, Mass Spectrometry and CHNS Determination
