摘要：

The recently introduced right-angle wiggling (RAW) EPR technique is applied to enhance the resolution of complicated high-spin EPR spectra. In particular, the RAW-EPR technique allows for a considerable resolution enhancement of orientationally disordered systems with anisotropic magnetic interactions and provides direct access to spin-Hamiltonian parameters without the need of numerical spectrum simulation. As an example of application, the Mn2+-functional centre in polycrystalline BaTiO3 is studied.
