I have calculated Z', Z", Z*, M', M", M*, Epsilon', Epsilon", Epsilon*, Rs, Rp, Cp, Conductivity and Admittance from the Impedance spectrosocpy. But I still have a problem in calculating the Arrehnius plot of the relaxation time from the Modulus spectra and Impedance spectra?. And also to plot dc conductivity and ac conductivity as a function of 1000/T? Which data should I take for the dc conductivity? and ac conductivity respectively?
