The widening and duplication, triplication, etc., of spectral lines when the radiations emanate in a strong magnetic field, first observed in 1896 by P. Zeeman, a Dutch physicist, and regarded as an important confirmation of the electromagnetic theory of light.
A shift in the energy levels of an isolated atom or molecule as a consequence of an external magnetic field. The energy levels of an atom (or molecule) depend on the internal forces that electrons and nuclei exert on each other as well as on any external forces (e.g., an electromagnetic field). An observable consequence of the Zeeman effect is the shifting and broadening of spectral lines. The Zeeman effect is the magnetic analogue of the Stark effect.
The broadening or splitting of spectral lines caused by the presence of a (strong) magnetic field in the gas where the lines are formed.
A situation in which a strong magnetic field can change the energy of subatomic energy states which are normally indistinguishable (degenerate energy states) so that their energy values become different. A splitting of the absorption lines which result from absorptions beginning or ending at such states, in the presence of a strong magnetic field.
The splitting of spectral lines when an external magnetic field is applied.
Zeeman effect is the splitting of the lines in a spectrum when the source of the spectrum is exposed to a magnetic field. It was discovered in 1896 by Pieter Zeeman (1865-1943).
A splitting of spectral lines in response to a magnetic field. It is used to measure magnetic field strengths on the Sun and on other astronomical objects. more
(a) The splitting of atomic spectral lines into two or more components in a transverse magnetic field. [DC99] (b) The splitting of spectral lines by a magnetic field. [A84](c) Line broadening due to the influence of magnetic fields. A multiplet of lines is produced, with distinct polarization characteristics. The Zeeman effect is measured by measuring the difference between right-hand and left-hand polarization across a spectral line. [H76
The Zeeman effect (IPA ) is the splitting of a spectral line into several components in the presence of a magnetic field. It is analogous to the Stark effect, the splitting of a spectral line into several components in the presence of an electric field. The Zeeman effect is very important in applications such as nuclear magnetic resonance spectroscopy, electron spin resonance spectroscopy, magnetic resonance imaging (MRI) and Mössbauer Spectroscopy.
