FTP, name this effect described as the splitting of spectral lines in a magnetic field.
If the factor g sub L, or the Lande g factor, is calculated then its results can be expressed in terms of the z-component of the total angular momentum. Its "anomalous" variety describes cases in which spin contributes, but in all cases it is caused by the exertion of a torque on the potential energy and the dipole. The standard variety results in an equally-spaced triplet, which is caused by the displacement of the energy levels.
