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. Suppose that a hydrogen atom is this type of energy-shift of an atomic state in the presence of a small electric field is known as the quadratic Stark effect. Note that this effect is specific to hydrogen, since in other elements the \(s\) and \(p\) levels are not degenerate. Experimental results confirm this theory beautifully - the splitting of levels in hydrogen varies linearly with the applied field strength, while in all other atoms it varies quadratically: the first order perturbation is zero.

The H–Cl vibrational bands of the HCl dimers showed a linear Stark frequency shift and an increased intensity under the Hence hydrogen-like atoms with n >1 show first-order Stark effect. The first-order Stark effect occurs in rotational transitions of symmetric top molecules (but not for linear and asymmetric molecules). In first approximation a molecule may be seen as a rigid rotor. A symmetric top rigid rotor has the unperturbed eigenstates The Stark Effect for n=2 Hydrogen. 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 451: First Order Degenerate Perturbation Theory - the Stark Effect of the Hydrogen Atom.
2018-8-26 · D. 80 Hydrogen ground state Stark effect This note derives the Stark effect on the hydrogen ground state. Since spin is irrelevant for the Stark effect, it will be ignored. The unperturbed ground state of hydrogen was derived in chapter 4.3. Following the convention in perturbation theory to append a subscript zero to the unperturbed state, it can be summarized as:
2010-7-20 · Returning to the Stark effect, let us examine the effect of an external electric field on the energy levels of the states of a hydrogen atom. There are four such states: an state, usually referred to as, and three states (with), usually referred to as 2P.
