Abstract
The quantum theory of local modes in molecules is extended to few-dimensional solids such as polyacetylene. Local modes are found to be present below the phonon band no matter how weak the anharmonicity. The problem of the local mode interacting with a phonon background is reduced to a Bose variety of the Kondo problem. Based on this analogy, a theory is constructed of thermal dissociation of local modes and the generation of high local-mode quantum numbers through intense radiation.
