Two different equations, both of which are often called ‘the Cole–Cole equation’, are widely
used to fit experimental Spectral Induced Polarization data. The data are compared on the
basis of fitting model parameters: the chargeability, the time constant and the exponent. The
difference between the above two equations (the Cole–Cole equation proposed by the Cole
brothers and Pelton’s equation) is manifested in one of the fitting parameters, the time constant.
The Cole–Cole time constant is an inverse of the peak angular frequency of the imaginary
conductivity, while Pelton’s time constant depends on the chargeability and exponent values.
The difference between the time constant values corresponding to the above two equations
grows with the increase of the chargeability value, and with the decrease of the Cole–Cole
exponent value. This issue must be taken into consideration when comparing the experimental
data sets for high polarizability media presented in terms of the Cole–Cole parameters.
