Abstract
Intra-configuration electric dipole transitions may occur for an ion in a crystal at a site that is not a center of inversion. When an external magnetic field is directed perpendicularly to the principal crystal symmetry axis c, intensity variations in the optical spectrum due to transitions between Zeeman states may appear as the crystal is rotated about c or as the direction of polarization of the incident light is changed with respect to the Zeeman field direction. The electric dipole selection rules giving rise to these intensity fluctuations are derived by consideration of Earney's mirror plane symmetry, and are shown to be identical to those obtained by other means.
