Note that the linear Stark effect depends crucially on the degeneracy of the and states. This degeneracy is a special property of a pure Coulomb potential, and, therefore, only applies to a hydrogen atom.

In the presence of a static external electric field the 2J+1 degeneracy of each rotational state is partly removed, an instance of a Stark effect. For example, in linear molecules each energy level is split into J+1 components. Notes 23: Stark Effect 5 6.

Hydrogen atom in electric field. Quadratic Stark effect. We consider a hydrogen atom in the ground state in the uniform electric field 2010-02-10 · History. The effect is named after Johannes Stark, who discovered it in 1913.It was independently discovered in the same year by the Italian physicist Antonino Lo Surdo, and in Italy it is thus sometimes called the Stark-Lo Surdo effect. The Stark effect is the electric analogue of the Zeeman effect where a spectral line is split into several components due to the presence of a magnetic field. The Stark effect can be explained with fully quantum-mechanical approaches, but it has also been a fertile testing ground for semiclassical methods.
