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.

Only the first‐order terms in the inhomogeneity of the field are retained. An examination of the symmetry of the Well, let us see. 1. When Bohr presented his famous model based on three postulates, he was glad that the spectrum of hydrogen clearly obeyed his ideas that the stationary orbits are indeed existent and the spectrum bands represent electronic tran namic Stark effect are discussed.

1 √2(2s − 2pz) E = ( − 0.125 + 3ε)Eh. Because the energy of the symmetric 1s state is unaffected by the electric field, the effect of this perturbation on the electronic spectrum of hydrogen is to split the n = 1 to n = 2 transition into three lines of relative intensity 1:2:1. < 2s | Hʹ | 2s > = 0.

Stark effect in hydrogen atom

2.1 Hydrogen atom in an electric field (Stark effect) To begin with, let us consider the well known and the simplest external field problem, namely the hydrogen atom in a static electric field. The Hamiltonian of the hydrogen The unperturbed eigenstates of a hydrogen atom have energies that only depend on the radial quantum number \(n\). (See Chapter .) It follows that we can only apply the previous results to the \(n=1\) eigenstate (because for \(n>1\) there will be coupling to degenerate eigenstates with the same value of \(n\) but different values of \(l\)). 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 effect for the n=2 states of hydrogen requires the use of degenerate state perturbation theory since there are four states with (nearly) the same energies. For our first calculation, we will ignore the hydrogen fine structure and assume that the four states are exactly degenerate, each with unperturbed energy of . That is .
