The effect was discovered in 1913 by J. Stark while studying the spectrum of the hydrogen atom. Observed in the spectra of atoms and of other quantum systems, it results from a shift of a quantum system’s energy levels and the splitting of the energy levels into sublevéis under the influence of an 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. Although initially coined for the static case, it is also used in the wider context to describe the effect of time-dependent electric fields.

Stark effect in hydrogen atom

We are often interested in the effect of an external electric field on the energy levels and wavefunction of H and other one-electron atoms so lets consider the atom in a spatially constant electric field. The energy shift due to the electric field is called the Stark effect. 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 #stark_effect_in_hydrogen_atom #AtomicPhysics #stark_effect_in_Hindi #weak_field_stark_effect #Strong_field_stark_effect #weak_and_strong_field_stark_effect The quantum-confined Stark effect is the Stark effect observed in structures in which the hydrogenic system is confined in a layer of thickness much less than its normal diameter.

Not to scale. Note, finally, that although expression ( [e12.137] ) does not have a well defined value for \(l=0\), when added to expression ( [e12.121] ) it, somewhat fortuitously, gives rise to an expression ( [e12.138] ) that is both well-defined and correct when \(l=0\) . While the Zeeman effect in some atoms (e.g., hydrogen) showed the expected equally-spaced triplet, in other atoms the magnetic field split the lines into four, six, or even more lines and some triplets showed wider spacings than expected. These deviations were labeled the "anomalous Zeeman effect" and were very puzzling to early researchers. The spectrum of a hydrogen atom in weak perpendicular and parallel electric and magnetic fields is analyzed, with allowance made for diamagnetic interaction. In both cases, the energy spectrum of the highly excited states as a function of the intensity of the electric field given a fixed magnetic field breaks down into three qualitatively different regions.

The Stark effect is a phenomenon by which the energy eigenstates of an atomic or molecular system are modified in the presence of a static, external, electric field. This phenomenon was first observed experimentally (in hydrogen) by J. Stark in 1913 [ 105 ]. Let us employ perturbation theory to investigate the Stark effect.
