The electron spin had not been discovered at the time of Zeeman’s original experiments, so the cases where it contributed were considered to be anomalous.
Oh no, there’s been an error
This type of splitting is observed for spin 0 states since the spin does not contribute to the angular momentum. But when the effects of electron spin were discovered by Goudsmit and Uhlenbeck, they found that the observed spectral features were matched by assigning to the electron spin a magnetic moment. It allowed them to express the resultant splittings of the spectral zeemqn in terms of the z-component of the total angular momentum, m j.
In the efectl dipole approximation, the Hamiltonian which includes both the hyperfine and Zeeman interactions is.
But when the effects of electron spin were discovered by Goudsmit and Uhlenbeck, they found that the observed spectral features were matched by assigning to the electron spin a magnetic moment where g is approximately 2.
Retrieved from ” https: When the Zeeman effect was observed for hydrogen, the observed splitting was consistent with an electron orbit magnetic moment given by.
First order perturbation theory with these fine-structure corrections yields the following formula for the Hydrogen atom in the Paschen—Back limit: Note that the transitions shown follow the selection rule which does not allow a change of more than one unit in the quantum number m l. It was called “anomalous” because the electron spin had not yet been discovered, and so there efedto no good explanation for it zeman the time that Zeeman observed the effect.
On the left, fine structure splitting is depicted. The energies are simply. This effect is the strong-field limit of the Zeeman effect. Julian—Gregorian uncertainty CS1 maint: The Zeeman effect for the hydrogen atom offered experimental support for the quantization of angular momentum which arose from the solution of the Schrodinger equation. Hydrogen Zeeman Example The Zeeman effect for the hydrogen atom offered experimental support for the quantization of angular momentum which arose from the solution of the Schrodinger equation.
In general, both orbital and spin moments are involved, and the Zeeman interaction takes the form.

The Paschen—Back effect is the splitting of atomic energy levels in the presence of a strong magnetic field. Wikimedia Commons eecto media related to Zeeman effect. The above may be read as implying that the LS-coupling is completely broken by the external field.
Also efrcto to the Stark effect, transitions between different components have, in general, different intensities, with some being entirely forbidden in the dipole approximationas governed by the selection rules.
The total Hamiltonian of an atom in a magnetic field is. Rashba, Combined resonance in crystals in inhomogeneous magnetic fields, Sov. Introduction to Quantum Mechanics 2nd ed.
Zeeman Interaction An external magnetic field will exert a torque on a magnetic dipole and the magnetic potential energy which results in The magnetic dipole moment associated with the orbital angular momentum is given by For a magnetic field in the z-direction this gives Considering the quantization of angular momentumthis gives equally spaced energy levels displaced from the zero field level by This displacement of the energy levels gives the uniformly spaced multiplet splitting of the spectral lines which is called the Zeeman effect.
Together with the selection rules for an electric dipole transitioni.
It is analogous to the Stark effectthe splitting of a spectral line into several components in the presence of an electric zeemzn. In general, one must now add spin-orbit coupling and relativistic corrections which are of the same order, known as ‘fine structure’ as a perturbation to these ‘unperturbed’ levels.
Zeeman Effect in Hydrogen
The persistent early spectroscopists worked zeejan a way to calculate the effect of the directions. It may also be utilized to improve accuracy in atomic absorption spectroscopy. In other projects Wikimedia Commons. These deviations were labeled the “anomalous Zeeman effect” and were very puzzling to early researchers.
