Transition from the deformed structure to the statistically equivalent ideal structure and an estimate of the basic physical characteristics of the deformed structure

A procedure is proposed enabling the substitution of a translationally non-invariant one-dimensional structure with unequal neighbouring spacing by a statistically equivalent ideal structure with equal spacing between neighbouring molecules. A procedure of statistical averaging of the intermolecular spacing is applied to some typical intermolecular potential in order to estimate its physical plausibility. The main conclusion is that non-ideality of the structure makes the transport of elementary excitations more difficult with respect to the same transport through the ideal structure.
