On the basis of the experimental data previously presented, the case is made for a unifying approach to the interpretation of the common dielectrie response of most solids. This approach starts from the unique property of this response tht the ratio to the energy lost per cycle to the energy stored in the system is independent of frequency. A “screened hopping” model involving many‐body interactions is proposed which has the requied generality and which should account for the commonly observed behaviour. The physical nature of the loss peaks is also interpreted in terms ofthe new model as the result of sequential interplay of the different types of decay processes in the time domain. The relation of the new model to the classical Debye picture is briefly discussed.
