T1 - On the dynamic response of impure molecular crystals

N2 - The total wave function of an impure molecular crystal is resolved, using the partitioning technique, into two components, one restricted to the host lattice and one which describes the interaction between the isolated impurities and the host. The two components differ by a phase which can be a rapidly varying function of the energy. Typical interference effects can thus be demonstrated when the linear response to an external perturbation is observed. A model of a one‐dimensional linear chain is considered and explicit results are obtained using an integral Hellmann‐Feynman theorem for two potentials.
