Its two-dimensional form can yield cascades when applied to quantum wires and it is particularly useful for molecular rotational spectra because its manifestations indicate low-J transitions.
In a plasma, it is proportional to the ion and electron density and is therefore a good indicator of the pressure of a star's atmosphere. Its two-dimensional form can yield cascades when applied to quantum wires and it is particularly useful for molecular rotational spectra because its manifestations indicate low-J transitions. In its quadratic form, the first-order terms vanish in accordance with the Wigner-Eckart theorem, but a linear case exists which depends on the degeneracy of the 2s and 2p states and thus is not exhibited by alkali atoms. For ten points, identify this effect which breaks degeneracy through the application of an electric field.
