Nuclear magnetic resonance (NMR) is a spectroscopic approach to observe local magnetic fields around certain nuclei being intrinsically magnetic. The NMR signals are generated by exciting nuclei with radio frequencies while being submitted to an external magnetic field. This is typically done in aqueous solution, but can also be performed with solid samples (see solid-state NMR).
More specifically, in structural biology, it is a method used for the determination of the three-dimensional molecular structure and dynamics of proteins and nucleic acids at atomic resolution. The results obtained from these measurements provide information about:

Alternatively, the Structural Biology Platform has computers available where recent versions of these softwares software programs are installed (TopSpin is only available on the computers controlling the spectrometers). Access to the computer room is controlled by access codes. Contact Normand Cyr in order to obtain a code.
