Zusammenfassung

The complex dielec. permittivity of aq. sodium carbonate solns. (0.05≤c/mol L-1≤2.5) has been detd. in the frequency range 0.2≤ν/GHz≤20 at 25.0°C with a com. dielec. measurement system based on a vector network analyzer. A superposition of three Debye relaxation processes was necessary to fit the complex permittivity spectra. The slow and intermediate dispersion steps are assigned to double ...
