Nuclear Magnetic Resonance Using a Spatial Frequency Encoding: Application to J‐Edited Spectroscopy along the Sample

Finger on the pulse: Selective experiments can be simultaneously run on different parts of the sample when NMR sequences based on a spatial encoding are used. This approach was applied to a gradient-encoded selective refocusing sequence. The resulting data provide a collection of all the couplings that involve a given proton spin, which can be conveniently assigned and measured from only one spectrum.
