Split in the spectral line when a magnetic field is applied.

Non-anomalous: number of splits matches predictions of the Schrodinger equation about the number of possible states with a given angular momentum. TODO does it make numerical predictions?

Anomalous: evidence of spin.

http://www.pas.rochester.edu/~blackman/ast104/zeeman-split.html contains the hello world that everyone should know: 2p splits into 3 energy levels, so you see 3 spectral lines from 1s to 2p rather than just one.

p splits into 3, d into 5, f into 7 and so on, i.e. one for each possible azimuthal quantum number.

It also mention that polarization effects become visible from this: each line is polarized in a different way. TODO more details as in an experiment to observe this.
