Since Fis constant ϕ=− ri F up to an arbitrary constant, which we ignore. Converting r e & r n to The physics of the optical Stark effect can be presented semi -classically by a Hamiltonian in which light is represented by classical fields as external perturbation. The perturbed Hamiltonian can be diagonalized to obtain the altered energy levels, and the optical Stark effect can be perceived from the induced change of the energy spectrum. The Stark effect does not provide the signs of the dipole components, and therefore the direction must be obtained from other information, such as electronegativities. However, the effect of isotopic substitution, where the primary effect is to rotate the principal axis system, has been used to specify the directions of the dipole components and hence μ.

We first consider the situation in which H' is zero and HO is simply the complete atomic Hamiltonian in zero electric field. In general, with this choice of Hamiltonian there is no degeneracy so that the Stark operators will have only diagonal matrix elements. Consider again the Stark effect Hamiltonian (1.1): H = H(F) =-Δ- Zlr + 2Fx 3. (2.1) It is well known [12,17] that the partial differential expression (2.1) can be realized Stark effect in the hyperfine components of J = 3 ← 2 rotational transition of IBr molecule has been investigated in the microwave region. As IBr possesses strong quadrupole coupling nuclei, the electric dipole moment of the molecule has been evaluated by diagonalizing the energy Hamiltonian. Stark effect has been measured on six M F > components at different field strengths.

The external electric field can be applied to an atom or molecule and acts as a perturbation.

The Hamiltonian for this perturbation in atomic units is: \[H^{\prime}= εz,\] which in spherical polar coordinates is: \[H^{\prime} = ε r\cos(θ),\] where \(ε\) is the electric field strength. In this perturbation method treatment the hydrogen atom eigenfunctions are used to evaluate the matrix elements associated with the total Hamiltonian, 8.3 Stark E ect The Stark e ect is the electric analogue to the Zeeman e ect, i.e., a particle carrying an electric dipole moment, like the H-atom, will get a splitting of its energy levels when subjected to an exterior electric eld.

* The perturbation to the exact Hamiltonian due to the application of the electric field is. Short article on the Stark Effect. Hamiltonian, when we apply an external electric field, can be expressed as a smaller "perturbation" on the main Hamiltonian:  our fruitful discussions concerning the theory of the Stark effect.
