A linear molecular polymer chain formed by replacing two host molecules by two identical impurities is investigated. Applying a particular theoretical approach the energies of localized excitations appearing in the system are determined and the dependence of these energies on the distance between the impurities is discussed. The theoretical approach is formulated in a way that reduces the problem to the analysis of an ideal polymer chain with some extra off‐diagonal terms in the Hamiltonian. These extra terms are considered as an interaction caused by the nonideality of the polymer chain.
