Normal Zeeman Effect vs. Anomalous Zeeman Effect — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on December 24, 2023
Normal Zeeman Effect splits spectral lines into equally spaced components due to the magnetic field. Anomalous Zeeman Effect shows uneven splitting due to both the magnetic field and electron spin.

Key Differences
The Normal Zeeman Effect pertains to the splitting of spectral lines in the presence of a magnetic field. The Anomalous Zeeman Effect, on the other hand, involves uneven splitting caused by both the magnetic field and electron spin.
When a spectral line, due to the Normal Zeeman Effect, undergoes splitting, it divides into equidistant components. The Anomalous Zeeman Effect displays a different behavior; spectral lines split in a manner that is not uniform, owing to the intrinsic electron spin.
To differentiate further, the Normal Zeeman Effect arises because of the orbital motion of electrons. Meanwhile, the Anomalous Zeeman Effect is a combined result of both the electron's orbital motion and its intrinsic spin.
One can observe the Normal Zeeman Effect when the net spin of the electrons in the atom is zero. For the Anomalous Zeeman Effect to be evident, the net spin of the electrons should not be zero, leading to complex and uneven spectral splitting.
For magnetic field effects on spectral lines, the Normal Zeeman Effect demonstrates simplicity and predictability. The Anomalous Zeeman Effect, conversely, is more intricate due to the interplay of the magnetic field and electron spin.
