The splitting of the spectral lines of an atom in the presence of an external electric 5. eld is known as the Stark eect. 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 \(l\)).

For each case the matching procedure was repeated many times with increased values We extend the procedure originally suggested by Dalgarno and Lewis in studying the second-order Stark effect for the ground-state hydrogen atom to the excited states. We solve the perturbation equations for the excited states of hydrogen atom placed in an external electric field to obtain expressions for the perturbed wavefunctions. atoms Article Atomic Data for Calculation of the Intensities of Stark Components of Excited Hydrogen Atoms in Fusion Plasmas Oleksandr Marchuk 1,* , David R. Schultz 2 and Yuri Ralchenko 3 1 Forschungszentrum Jülich GmbH, Institut für Energie- und Klimaforschung - Plasmaphysik, Partner of the Trilateral Euregio Cluster (TEC), 52425 Jülich, Germany Zeeman Effect in Hydrogen When an external magnetic field is applied, sharp spectral lines like the n=3→ 2 transition of hydrogen split into multiple closely spaced lines. First observed by Pieter Zeeman, this splitting is attributed to the interaction between the magnetic field and the magnetic dipole moment associated with the orbital angular momentum. Therefore $\Delta E_0=0$, there is no first-order shift in the ground state of hydrogen, i.e. there is no linear Stark effect. (You could also try to show, by the same sort of reasoning, that there is no linear Stark effect for any atom in a non-degenerate energy eigenstate).

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.

Hence, hydrogen-like atom with n>1 shows first-order Stark effect. The first-order Stark effect occurs in rotational transitions of symmetric top molecules (but not for linear and asymmetric molecules).
