Abstract
THE S D transitions which occur in the alkali spectra are forbidden by the ordinary selection rules for the azimuthal quantum number. As they are still observable in absorption, the question arises whether they are due to the action of external electric fields and are still a dipole radiation from a perturbed atom, or whether they are due to quadripole radiation. Rubinowicz has calculated the Zeeman selection rules for quadripole radiation; they differ from the ordinary rules in that the change in the magnetic quantum number may have the values +mn2 in addition to the ordinary ones 0, +mn1. The polarisation also is quite different.
