Abstract :
We have outlined a possible explanation for the observed compensation law in TSDC experiments. The existence ofa current peak in TSDC implies a relationship between the adimensionalised activation enthalpy and entropy. Thus, when the activation entropy of a relaxation process increases the enthalpy will also increase necessarily in order that the peak temperature remains more or less in the same region
