Zeeman Spectroscopy

Definition

Zeeman spectroscopy is a technique used to analyze the splitting of spectral lines of atoms and molecules when they are subjected to a magnetic field. This splitting occurs due to the interaction between the magnetic field and the magnetic moments of the electrons, providing insights into atomic structure and energy levels. The observations made through this technique can reveal important information about fine structure and electronic transitions within atoms.
