Paramagnetic metal ions affect the NMR spectra of molecules. The hyperfine shift is the difference between the chemical shift of a nucleus in a paramagnetic molecule and that in the diamagnetic analog obtained after removal of the paramagnetic metal ion, its substitution with a diamagnetic ion, or reduction/oxidation of the paramagnetic metal to a diamagnetic state. The hyperfine shift comprises the contact and the pseudocontact shifts.

Abstract
Paramagnetic metal ions affect the NMR spectra of molecules. The hyperfine shift is the difference between the chemical shift of a nucleus in a paramagnetic molecule and that in the diamagnetic analog obtained after removal of the paramagnetic metal ion, its substitution with a diamagnetic ion, or reduction/oxidation of the paramagnetic metal to a diamagnetic state. The hyperfine shift comprises the contact and the pseudocontact shifts.
