Such a splitting of lines is called the normal Zeeman effect. According to the oscillation model by Hendrik Lorentz, the Zeeman splitting arises from the oscillation of charged particles in atoms. The discovery of the Zeeman effect.
Kapitel 12 Der Zeeman-Effekt. In diesem Kapitel befassen wir uns mit dem Einfluss eines externen Magnetfelds auf das Spektrum eines Atoms. Wir werden sehen, dass infolge dieser Beeinflussung die Entartung der Energieniveaus teilweise aufgehoben wird und als Folge davon die einzelnen Spektrallinien in mehrere Linien aufgespaltet werden. Der Zeeman-Effekt [ˈzeːmɑn-] ist in der Atomphysik die Aufspaltung von Spektrallinien durch ein Magnetfeld.
Die Aufspaltung entsteht durch die unterschiedliche Verschiebung von Energieniveaus einzelner Zustände unter dem Einfluss eines äußeren Magnetfelds. Erstmals wurde der Effekt von Pieter Zeeman nachgewiesen.

Ina Dutch physicist Pieter Zeeman, succeeded to partially explain the experimental results. He showed that the spectral line splitting can be classiﬁed in, what is today known as, the normal Zeeman eﬀect and the anomalous Zeeman eﬀect.
While the normal Zeeman eﬀect wasin agreementwith the classicaltheory developed. Magnetic splitting (nuclear Zeeman effect) is caused by the magnetic dipole interaction between the nuclear spin moment and the internal magnetic field (H int) at the nucleus.
In the case of 57 Fe, the transitions between the excited and ground states are limited by the selection rule of Δ m = 0, ±1, and the Mössbauer spectrum shows a magnetically split sextet. Pieter Zeeman (–) had been searching for the influence of magnetic fields on spectral lines since Michael Faraday's (–) demonstration of the rotation of the plane polarization of light in electric fields had led Faraday himself and several other experimenters to expect such an influence.

Zeeman effect of R-lines in ruby is obtained by applying a magnetic field, H 0 parallel and perpendicular to the crystallographic C-axis i.e C 3-axis.
The ground quartet state 4 A 2 splits with g 0 = and g 0 =respectively, where // and ⊥ are refered to the trigonal C 3 -axis.(10) The small initial splitting of cm −1 in the ground state is neglected. Zeeman’s discovery earned him the Nobel Prize for Physics, which he shared with a former teacher, Hendrik Anton Lorentz, another Dutch physicist.
Lorentz, who had earlier developed a theory concerning the effect of magnetism on light This theory was confirmed by Zeeman’s research and later modified by quantum mechanics 4. The Zeeman E ect is the splitting of a spectral line in the presence of a static magnetic eld. This is due to the magnetic eld breaking the degeneracy of electron con gurations with the same energy.

Zeeman effect, in physics and astronomy, the splitting of a spectral line into two or more components of slightly different frequency when the light source is placed in a magnetic abzt.prodecoring.ru was first observed in by the Dutch physicist Pieter Zeeman as a broadening of the yellow D-lines of sodium in a flame held between strong magnetic poles.
Later the broadening was found to be a. The Zeeman Effect In P. Zeeman reported his discovery that atomic spectral lines split into multiplets when the atoms are placed in a magnetic field. A high-resolution spectrometer and/or a very strong magnet are needed to observe the effect since the splitting is normally only about cm-1/T (1 tesla = gauss).
Zeeman effect A splitting of the energy terms of atoms in a magnetic field can be observed as a splitting of the frequencies of transitions in the optical spectra (or as a shift). A splitting of this type of spectral lines in a magnetic field was observed for the first time in by Zeeman. Key Difference – Normal vs Anomalous Zeeman Effect Inthe Dutch physicists Pieter Zeeman observed the splitting of spectral lines emitted by atoms in sodium chloride, when it was kept in a strong magnetic abzt.prodecoring.ru simplest form of this phenomenon was introduced as normal Zeeman effect.

Abstract. In this work we study the Zeeman effect on stratospheric O 2 using ground-based microwave radiometer measurements. The interaction of the Earth magnetic field with the oxygen dipole leads to a splitting of O 2 energy states, which polarizes the emission spectra.
A special campaign was carried out in order to measure this effect in the oxygen emission line centered at GHz.
