This technique can be used to measure distances using observations of an associated through space dipole-dipole interaction known as the Overhauser effect.  The coupling constant associated with this technique is related to the torsion angle by Karplus's equation.  Some samples observed using this technique show induced ring currents that produce observable shielding.  Measurements involve calibration using a reference compound such as TMS and determination of the chemical shift.  FTP, name this technique involving transitions between spin states of nuclei in an applied field.
