That effect forms the basis for the NOESY version of this technique, which along with HNQC and COSY are two-dimensional versions of it.  
The analysis of one form of this technique relies on sequential walking for the correct assignment of crosspeaks, which are generated in the Overhauser effect.  That effect forms the basis for the NOESY version of this technique, which along with HNQC and COSY are two-dimensional versions of it.  In solid state forms of it, the magic angle reduces unwanted effects, while desired effects include the induction of Larmor precession, the decay of which gives rise to signals that are split into multiplets based on spin-spin coupling and measured in chemical shift.  For 10 points, name this spectroscopic technique that begins with the alignment of nuclei in a strong magnetic field.
