Stark-effect study of excited states in sodium using two-photon spectroscopy. / Hawkins, R. T; Hill, W. T; Kowalski, F. V; Schawlow, A. L; Svanberg, Sune.


in 1919 "for his discovery of the Doppler effect in canal rays and the splitting of spectral lines in electric fields". This phenomenon is known as the Stark effect.

In terms of the quantum numbers these states are , , , and . Hence, this type of energy-shift of an atomic state in the presence of a small electric field is known as the quadratic Stark effect. Now, the electric polarizability of an atom is defined in terms of the energy-shift of the atomic state as follows : ΔE = − 1 2 α | E | 2. Hence, we can write αnlm = 2e2 ∑ n. ′. , l.

Only a discrete set of frequencies of light may be absorbed or emitted by the system. When an external electric field is applied, the electron states shift to lower Stark effect is observed in many natural and artificial plasmas and is of great importance for diagnostic purposes.

2021-04-09 The Stark effect does not provide the signs of the dipole components, and therefore the direction must be obtained from other information, such as electronegativities. However, the effect of isotopic substitution, where the primary effect is to rotate the principal axis system, has been used to specify the directions of the dipole components and hence μ.

The quadratic Stark effect is basic to the explanation of the formation of molecules from atoms, of dielectric constants, and of the broadening of spectral lines. The intermolecular Stark effect is produced by the action of the electric field from surrounding atoms or ions on the emitting atom.
