One form of this technique is followed by sequential walking and uses the Nuclear Overhauser effect. A two-dimensional type of this technique is called COSY. This procedure produces data expressed in parts per billion and is affected by J-coupling. Often using tetramethylsilane as a reference compound, one type of this technique is enhanced by cross-polarization while another type requires deuterated solvents. It comes in proton and carbon-13 varieties and produces a graph with absorption peaks created by chemical shifts. For 10 points, name this spectroscopic method for determining chemical structures by applying a magnetic pulse.
