The Dirac equation and anomalous magnetic moment

The idea of determining the magnetic resonance condition in a rotating frame of reference is being studied. In this frame, the rotating magnetic field should be at rest. The 3D transformation that determines the transition to the frame is found. The Dirac equation in a rotating electromagnetic field after such a transition is obtained. The magnetic resonance condition is determined by the stationarity of solutions. The connection between g-factor in the anomalous magnetic moment and a constant in 3D transformation is established.
