- Magnetic anisotropy in NMR can be described as follows12:
- The resonance frequency of a nuclear spin depends on the strength of the magnetic field at the nucleus, which can be modified by isotropic and anisotropic interactions.
- The effect of the pseudocontact term arises from magnetic anisotropy of the paramagnetic center, which creates a magnetic field that supplements that of the instrument's magnet.
- The magnetic field exerts its effect with both angular and a 1/r 3 geometric dependences.
