Abstract
The spectroscopic properties of octahedrally coordinated Ni2+ ions in Gd3Ga5O12 garnet are described with a five-parameter model in the fram ework of the adiabatic approximation. The effect of spin-orbit couplin g on the vibronic potentials due to the fully symmetric vibration is p ointed out. Values of parameters useful for comparison with previous w orks, such as a pseudo-Huang-Rhys parameter or the ''phonon'' energies of the levels, are given.
