ZEEMAN EFFECT Meaning and
Definition
-
The Zeeman effect refers to the splitting and shifting of spectral lines observed when atoms or ions in a magnetic field undergo transitions between different energy levels. This phenomenon was discovered by the Dutch physicist Pieter Zeeman in 1896.
When an external magnetic field is applied to an atom or ion, the energy levels associated with its orbiting electrons are modified. As a result, instead of having a single energy level for a specific electronic transition, each level is further split into multiple levels. This splitting appears as a series of closely spaced spectral lines in the atomic or molecular spectrum.
The Zeeman effect manifests in two distinct ways: the normal Zeeman effect and the anomalous Zeeman effect. In the normal Zeeman effect, the spectral lines divide into three components: one central or "normal" component, and two side components known as "sigma" components. The separation between the three lines depends on the strength of the applied magnetic field.
On the other hand, the anomalous Zeeman effect occurs when there are multiple valence electrons with angular momentum. In this case, the spectral lines divide into more than three components, and the spacing between them may be unequal.
The Zeeman effect has profound implications in atomic physics, astrophysics, and quantum mechanics. It provides crucial insights into the behavior of atoms and ions in the presence of magnetic fields, allowing scientists to study the structure and properties of matter in various research fields.

Etymology of ZEEMAN EFFECT
The word Zeeman effect is named after the Dutch physicist Pieter Zeeman (1865-1943), who discovered and investigated this phenomenon in 1896. Pieter Zeeman received the Nobel Prize in Physics in 1902 for this discovery, which was an important contribution to the field of atomic and quantum physics. The effect refers to the splitting and polarization of spectral lines in the presence of a magnetic field, and it has significant implications for the understanding of atomic structure and behavior. Therefore, to honor Zeeman's groundbreaking work, the scientific community named this phenomenon the Zeeman effect.
