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 spa cing by a statistically equivalent ideal structure with equal spacing between neighbouring molecules. A procedure of statistical averaging o f the intermolecular spacing is applied to some typical intermolecular potential in order to estimate its physical plausibility. The main co nclusion is that non-ideality of the structure makes the transport of elementary excitations more difficult with respect to the same transpo rt through the ideal structure.
