Summary

[edit]
Description
English: A comparison between high-field and zero-field NMR spectra of a sample containing a mixture of [2-13C]-acetic acid and [2-13C]-bromoacetic acid. In the high field, the 1H and 13C nuclear spins species precess at different frequencies, yielding distinct 1H and 13C spectra with the J-coupling perturbation splitting the resonance into doublet, triplet or quartet multiplet patterns. At zero field, there is no Larmor precession and the resonance frequencies are determined principally by the J-couplings. Another notable feature is the narrow line width at zero field, owing to a lack of inhomogeneous broadening.
