The Stark effect is the shifting and splitting of spectral lines of atoms and molecules due to the presence of an external electric field. It is the electric-field analogue of the Zeeman effect , where a spectral line is split into several components due to the presence of the magnetic field .

2020-08-17 · The Stark effect is the shifting and splitting of spectral lines of atoms and molecules due to the presence of an external static electric field. The amount of splitting and or shifting is called the Stark splitting or Stark shift. In general one distinguishes first- and second-order Stark effects. Stark Effect in Atomic Spectra. The splitting of atomic spectral lines as a result of an externally applied electric field was discovered by Stark, and is called the Stark effect.

Stark effect notes

Note that the energy shifts are linear in the electric field-strength, so this effect--which is known as the linear Stark effect--is much larger than the quadratic effect described in Sect. 12.5. Note, also, that the energies of the and states are not affected by the electric field to first-order.

This phenomenon is usually referred to as the Stark effect, though some Italian authors prefer to call it ‘Stark-Lo Surdo effect’, because Antonio Lo Surdo (1880–1949) independently also found this The Stark effect is the shifting and splitting of spectral lines of atoms and molecules due to the presence of an external static electric field. The amount of splitting and or shifting is called the Stark splitting or Stark shift. In general one distinguishes first- and second-order Stark effects. Note in particular that the electronic center of charge has moved from the origin, which means the states have nonzero dipole moments.

Note that if fields are present, M is selected instead of J and the symmetry is ignored. As a simple example, consider the Stark effect in a symmetric top with B = 10 cm-1, C = 6 cm-1 and a dipole of 1.5 Debye, approximately those of NH 3. (Note that the inversion doubling makes the true picture in NH 3 more complicated - see NH3 pure rotation.

The theory of the Stark effect in atomic spectra is discussed in general terms and it is shown that large effects arise when two terms which are related to each other in such a way as to satisfy the optical combining rules come close together in the spectrum. Fairly good values of the Stark displacements in complicated atoms may be obtained simply by using the hydrogenic values of the matrix components involved in the theoretical formulas. The Stark effect is responsible for the pressure broadening ( Stark broadening) of spectral lines by charged particles. When the split/shifted lines appear in absorption, the effect is called the inverse Stark effect . The Stark effect is the electric analogue of the Zeeman effect where a spectral line is split into several components due to the presence of a magnetic field.
