The optical Stark effect as applied to molecular transition frequencies has been of considerable interest in recent years. 1 In particular, the ac Stark shift has been found to contribute to the linewidth broadening of the Stokes and anti-Stokes lines generated by stimulated Raman frequency conversion, 2 and influence the ultimate resolution limits and sensitivities of spectroscopic techniques such as stimulated Raman gain spectroscopy and CARS. 3 Also, transient changes in the index of

The effect of a static external electric and/or magnetic field can be included in PGOPHER simulations. Setting up a data file in principle only requires making sure the required electric or magnetic dipole moments for the state(s) of interest are present. 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 semi classical methods.

We have solved the Hydrogen problem with the following Hamiltonian.
This phenomenon was first observed experimentally (in hydrogen) by J. Stark in 1913 . Let us employ perturbation theory to investigate the Stark effect.

He claimed that an electric field would deform the Stark Effect. 108 likes.

In the absence of an external electric field, electrons and holes within the quantum well may only occupy states within a discrete set of energy subbands. Only a discrete set of frequencies of light may be absorbed or emitted by the system. Stark effect. The effect of an electric field on spectrum lines. The electric field may be externally applied; but in many cases it is an internal field caused by the presence of neighboring ions or atoms in a gas, liquid, or solid. Discovered in 1913 by J. Stark, the effect is most easily studied in the spectra of hydrogen and helium, by observing the light from the cathode dark space of an electric discharge.
The Stark effect can be explained with fully quantum mechanical approaches, but it has also been a fertile testing ground for semi classical methods. optical Stark effect, and later compare with the quantum picture. 2.1 Semi-classical physics of the optical Stark effect Figure 1.

The quantum-confined Stark effect describes the effect of an external electric field upon the light absorption spectrum or emission spectrum of a quantum well. In the absence of an external electric field, electrons and holes within the quantum well may only occupy states within a discrete set of energy subbands. Only a discrete set of frequencies of light may be absorbed or emitted by the system. When an external electric field is applied, the electron states shift to lower Stark effect is observed in many natural and artificial plasmas and is of great importance for diagnostic purposes. Since this effect alters profiles of spectral lines, it should be taken into 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.
