Crystal Zeeman effect

The secular determinantal equation is set up in the usual manner, the wavefunctions corrected for the crystal-field interaction are used in the perturbation treatment, energies are generated, and these are used in conjunction with the secular equations to generate new wavefunctions that have now been corrected for spin-orbit coupling. These corrected wavefunctions are used for the calculation of the Zeeman effect.

The third important hyperfine interaction is the nuclear Zeeman effect. This will occur if there is a magnetic field in and around the nucleus. The magnetic field H 0) can originate either within the atom itself or within the crystal via lattice exchange interactions.
