Breit-Rabi Diagram
Breit-Rabi Diagram
When a system of two spins (here and ) whose associated magnetic moments are coupled by the hyperfine interaction is exposed to a magnetic field , the energies of the magnetic sublevels depend in a nonlinear manner on The diagram representing the magnetic field dependence of the sublevel energies is known as a Breit-Rabi diagram. It is shown here in a universal form by using dimensionless field and energy scales.
