Zeeman Effect and Its Potential in Molecular Spectroscopy

Megan Climer

The Zeeman Effect is a splitting of energy levels or shells within an atom that is caused by an external magnetic field exerting torque on the electrons in the atom. The splitting itself is proportional to the strength of the magnetic field applied while the number of splits depends on the energy level of the atom itself. These splits can be observed in spectroscopy as distinct spectral lines that are formed in the place where only one was before. Studying this difference due to the magnetic field allows us to further understand the nature of the substance being studied as well as the subatomic particles that make it, which is especially true within molecules. Studying the effect there can lead to a better understanding of the bond between atoms as well as the atoms themselves.
