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. The stark effect on ground state of Hydrogen. When considering the Stark Effect, we consider the effect of an external uniform weak electric field which is directed along the positive z -axis, ε → = ε k →, on the ground state of a hydrogen atom. 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 the report the Stark effect for the ground state of a hydrogen atom is studied using perturbation theory. First parabolic coordinates are introduced for the hydrogen atom without an external electric field and the Schrödinger equation for movement of the electron in three and two dimensions respectively is solved analytically to find the energy and the eigenstates.
Since spin is irrelevant for the Stark effect, it will be ignored. The unperturbed ground state of hydrogen was derived in chapter 4.3.
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. Although initially coined for the static case, it is also used in the wider context to describe the effect of time-dependent electric fields. In particular, the Stark effect is responsible for the pressure b
The substitution of the dynamics of special relativity for classical dynamics in the problem of the unperturbed hydrogen atom led Sommerfeld to his well-known theory of the fine-structure of the levels; thus, in the absence of external fields, the state n = 1 (n = 2 in the old notation) is found to consist of two levels very close together, and n = 2 of three, so that the line H α of the 2019-02-16 The linear Stark effect is characteristic of hydrogen in electric fields that are not too strong. For example, in fields of ~10 4 volts per cm (V/cm), the effect amounts to a few thousandths of an electron volt. An energy level of a hydrogen atom with a given principal quantum number n is split symmetrically into 2n – 1 equidistant sublevéis (Figure 1 corresponds to n = 3, 2n – 1 = 5).

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. The Stark Effect of the Fine-Structure of Hydrogen.
