A two-dimensional form of
A two-dimensional form of this technique is able to calculate the distance between two atoms of interest by making use of a phenomenon caused by cross-relaxation. Relating peak integrals in this technique can determine the number of atoms of each element in the compound being studied. Deuterated chloroform is a common solvent in this technique, in which tetramethylsilane is often used as a standard with a 0 ppm chemical shift. Both the carbon-13 and proton variants of this technique rely on the magnetic moments of atoms changing in response to a magnetic field. For 10 points, name this spectroscopic technique which relies on a phenomenon also used in MRIs.
