Abstract
The values calculated for the side chain oscillator interaction energy for the polyene superconductor model have been revised. The use of parallel and perpendicular transitions gives a value for the naphthalene oscillator of 2.1 eV, well within the postulated range for a possibly operable effective interaction. The macromolecular superconductor concept proposed by Little [1] has been considered from a variety of theoretical points of view. Most of the objections [2-10] which have been suggested seem to be answerable [1, 11] in an acceptable manner. Thus, it does not seem to be essential to require one-dimensionality [4], and the unscreened model [6] gives interaction differentials much too high (above the ionization potential). Also, the thermodynamics of the situation are difficult, if not impossible, to evaluate if the transition occurs at high temperatures. The basic concept, that of electron-electron interaction, appears to present a theoretically valid alternative to the phonon-electron model for the BCS theory of metallic superconductivity.
