The world's most powerful NMR spectrometer

ists of several superconducting coils surrounded by an outer dewar containing liquid helium. Atomic nuclei of molecules inside the tube give detectable responses to a radio frequency signal emitted by the inner coil at varying "resonance" frequencies.

A typical experiment involves scanning a range of frequencies and recording the responses of the atoms in the sample. These responses are influenced by the shape of the molecule in which the atoms reside by their proximity to other atoms in the molecule. An NMR spectrum is unique for a particular molecule, and the structure of a molecule can be determined from its spectrum.
