Paper Abstract
The dielectric loss spectrum of liquid salt solutions consists of a conductivity and a relaxational contribution, and the latter can eventually be described by distinguishable spectral components. Here the lowest frequency component is considered which is due to ionic processes. Comparing a variety of solutions it is found that the respective relaxation times are in accord with the tumbling motion of solvent shared ion pairs in some cases. In others, however, they tend to comply with an upper limit correlated to the solution viscosity in a manner which seems to indicate a relaxation mechanism of general nature.
