The results of this technique are interpreted by tree diagrams, where each branch is separated by a distance labelled  J . This technique applies a Fourier transform to the free induction decay profile. The n -plus-1 rule predicts signals in this technique occur in ratios like 1-to-2-to-1 or 1-to-3-to-3-to-1. This technique's apparatus is a superconductor suspended in a dewar of liquid helium, suspended in a dewar of liquid nitrogen. Since heavy water is undetectable in this technique, it or deuterated (*)  chloroform is used as the solvent. This technique works for any atom with an odd number

This technique works for any atom with an odd number of protons plus neutrons; usually, however, it uses carbon-13 or hydrogen. For 10 points, name this technique that applies a strong magnetic field to a sample to induce spin flips, which is used in MRIs.
