Dynamics of molten CF3SO3H·H2O probed by temperature dependent dielectric spectroscopy

Barthel, Josef ; Buchner, Richard ; Hölzl, C. ; Conway, B.E.


The complex permittivity of CF3SO3H·H2O was studied in the frequency range 0.3-89 GHz at 298-338 K The microwave spectra which show very broad absorption are analyzed in terms of four Debye processes with relaxation times τ1>τ2>τ3>τ4. Whereas τ2, τ3 and τ4 exhibit Arrhenius behavior at all temps., the relaxation time of the slowest process, τ1, exhibits an unusual temp. dependence which can be ...
