The Stark e ect is the electric analogue to the Zeeman e ect, i.e., a particle carrying an electric dipole moment, like the H-atom, will get a splitting of its energy levels when subjected to an exterior electric eld. The Hamiltonian of the H-atom thus has (another) additional term, the Stark term H Stark, which is perturbing the Coulomb Hamiltonian H

This application of perturbation theory was its first use in quantum mechanics. From: Stark effect in A Dictionary of Chemistry » 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.

Stark effect 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.
