The dependences of thermoimpedance Z(phi) on overvoltage eta under the
potentiostatic regime are calculated on the basis of the previously d
eveloped theory of thermoimpedance. The results are compared with the
data obtained experimentally for the [Fe(CN)(6)](-3/-4) redox system.
Voltammograms for Z(eta) at a constant overvoltage are calculated usin
g the experimentally measured Z(phi) vs. eta curves and the correspond
ing dependences for the electrochemical admittance. The nature of the
eta dependences of Z(phi) and Z(eta) is shown to depend significantly
on the frequency of temperature modulation.
