The Zeeman effect is the effect of splitting of a spectral line into several components in the presence of a static magnetic field. It is named after the Dutch physicist Pieter Zeeman, who discovered it in 1896 and received a Nobel prize for this discovery. It is analogous to the Stark effect, the splitting of a spectral line into … See more Historically, one distinguishes between the normal and an anomalous Zeeman effect (discovered by Thomas Preston in Dublin, Ireland ). The anomalous effect appears on transitions where the net spin of the electrons is … See more The Paschen–Back effect is the splitting of atomic energy levels in the presence of a strong magnetic field.
