Abstract
The superspace description of incommensurable crystals is used to calc ulate the symmetry adapted crystal field potential for an incommensura ble crystal. With this crystal field potential the perturbation of the high temperature phase energy levels by the incommensurable modulatio n can be calculated using perturbation theory. The results of such cal culations on ThBr4 are compared with the experimental results obtained from optical and magnetic resonance spectroscopy.
