Differbetween
The anomalous effect appears on transitions where the net spin of the electrons is non-zero. It was called "anomalous" because the electron spin had not yet been discovered, and so there was no good explanation for it at the time that Zeeman observed the effect.

Why is the Zeeman effect important?
The Zeeman effect has helped physicists determine the energy levels in atoms and identify them in terms of angular momenta. It also provides an effective means of studying atomic nuclei and such phenomena as electron paramagnetic resonance.
What do you mean by Zeeman and anomalous Zeeman effects?
The “Zeeman effect” is the energy shift of atomic states caused by an magnetic field. ... This leads to a more complicated behaviour of the atom- ic states in an outer magnetic field. This is called anomalous Zeeman Effect and can be observed in atomic transitions where non-singulett states are involved.
Why is normal Zeeman effect observed in a strong magnetic field?
o Occurs in atoms with non-zero spin => atoms with odd number of electrons. o In an applied B-field, J precesses about B at the Larmor frequency. o L and S precess more rapidly about J to due to spin-orbit interaction. Spin-orbit effect therefore stronger.
What truth was explained by Zeeman effect?
Zeeman effect, splitting of a single spectral line (see spectrum) into a group of closely spaced lines when the substance producing the single line is subjected to a uniform magnetic field. The effect was discovered in 1896 by the Dutch physicist Pieter Zeeman.
What is the Zeeman effect and Stark effect?
Stark effect is the shifting and splitting of spectral lines of atoms and molecules due to presence of an external electric field. ... Zeeman effect is the effect of splitting a spectral line into several components in the presence of a static magnetic field.
How many types of Zeeman effect are there?
The spectral lines of mercury vapor lamp at wavelength 546.1 nm, showing anomalous Zeeman effect. (A) Without magnetic field. (B) With magnetic field, spectral lines split as transverse Zeeman effect. (C) With magnetic field, split as longitudinal Zeeman effect.
What is difference between normal and anomalous Zeeman effect?
The main difference between normal and the anomalous Zeeman effect is that normal Zeeman effect results in the formation of triplets by splitting a spectral line into three lines whereas anomalous Zeeman effect results in different splitting patterns from splitting of spectral lines.
What is the significance of Lande g factor?
In atomic physics, the Landé g-factor is a multiplicative term appearing in the expression for the energy levels of an atom in a weak magnetic field. The quantum states of electrons in atomic orbitals are normally degenerate in energy, with these degenerate states all sharing the same angular momentum.
What do you mean by Larmor precession?
Larmor precession(Noun) The precession of the motion of charged particles, or particles having a magnetic moment, in a magnetic field. Etymology: From Joseph Larmor, Irish physicist.
