摘要：

Extensive investigation of polycrystalline pyridinium hexafluorophosphate and its perdeuterated analog was performed by neutron scattering, NMR, and dielectric methods in a wide temperature range. The results of different spectroscopic methods enabled us to propose a general model of both ion reorientations and to determine their activation parameters. The aging effects observed slightly change the hindering barriers and significantly affect the phase transition temperature and the pyridinium cation dynamics.
