Its magnitude is inversely proportional to the (*) sixth power of the distance, but its effects are negligible when the distance exceeds four angstroms.
This phenomenon can only be observed in solution-like environments where isotropic rotational averaging eliminates the dependency of the magnitude on the angle. Its magnitude is inversely proportional to the (*) sixth power of the distance, but its effects are negligible when the distance exceeds four angstroms. Generating this effect requires the use of two resonance frequencies, with one being continuously emitted. Essentially a form of magnetic dipole coupling, it differs from J-coupling in that the protons involved act through space as opposed to bonds. For 10 points, name this effect which causes nuclear relaxation during an NMR or MRI and is the basis of the NOESY technique.
