Abstract

Dielec. relaxation spectroscopy (DRS) has been chosen to study the dielec. properties of ionene bromides and fluorides in water. The best model for describing the exptl. data in the range of frequencies 0.05 < v/GHz < 89 was the one that considered two relaxing species: (i) counterions and (ii) the bulk water. From the redn. of the water amplitude, S2, effective hydration nos. could be derived. ...
