Résumé en anglais

We propose to verify the Kramers-Kronig Relations (KKR) through comparison of two versions of the Distribution of Relaxation Times (DRT), calculated from the real and imaginary part of the impedance. When checking the integrity of impedance spectroscopy data, this method is useful to interpret correctly results when a direct calculation of the KKR integrals shows a deviation from measured data. Our method can distinguish cases (i) where a deviation from the KKR indicates genuine physical problems during the measurement from (ii) a deviation arising when the frequency range accessible by the measurement is insufficiently large.< Réduire
