Abstract
The angular dependence of the EPR spectrum of a tetragonal (in the paramagnetic phase) Gd3+-O2− center with large initial splitting is used to determine the rotation angles of the neighboring chlorine octahedron, which are related to the components of rotation modes, in the vicinity of room temperature. Aspects of the anomalous broadening of the EPR lines near structural transformations are discussed.
