The normal Zeeman effect occurs when there is no spin magnetic moment – states with zero spin are necessary. In singulett systems the spins of the electrons cancel each other i.e. add up to zero. ... This is called anomalous Zeeman Effect and can be observed in atomic transitions where non-singulett states are involved.

Normal Zeeman Effect
For singlet states, the spin is zero and the total angular momentum J is equal to the. orbital angular momentum L. When placed in an external magnetic field, the energy. of the atom changes because of the energy of its magnetic moment in the field, which. is given by.
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.
How is Zeeman splitting calculated?
The splitting between the two energy states is called electron Zeeman interaction (EZI) and is proportional to the magnitude of B0, as illustrated in Figure 1. The energy difference between the two Zeeman states is given by ΔE = E(mS = +1/2) - E(mS = -1/2) = geβeB0/h (in Hz).
What is Paschen Back effect?
: a limiting stage of the Zeeman effect which occurs as the magnetic field causing it is greatly increased and in which the extremely fine structure pattern after going through more or less complicated anomalous stages again approaches a normal triplet character.
What is Zeeman effect?
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 field.
What is 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.
What are the normal and anomalous Zeeman effects?
The normal Zeeman effect occurs when there is no spin magnetic moment – states with zero spin are necessary. In singulett systems the spins of the electrons cancel each other i.e. add up to zero. ... This is called anomalous Zeeman Effect and can be observed in atomic transitions where non-singulett states are involved.
What causes the Zeeman effect?
The reason for the Zeeman effect is that in a magnetic field, the angular momentum quantum state can undergo a displacement from degeneracy. ... The effect is due to the distortion of the electron orbitals because of the magnetic field. The (normal) Zeeman effect can be understood classically, as Lorentz predicted.
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.
Why do spectral lines split in magnetic fields?
Since electrons are charged, their intrinsic spin creates an intrinsic magnetic field Bint, which interacts with their orbital magnetic field Borb. ... Each spin direction has a different energy; hence, spectroscopic lines are split into two. Spectral doublets are now understood as being due to electron spin. Figure 5.
What causes hyperfine splitting?
Hyperfine coupling is caused by the interaction between the magnetic moments arising from the spins of both the nucleus and electrons in atoms. ... This spin interaction in turn causes splitting of the fine structure of spectral lines into smaller components called hyperfine structure.
