Helical Peierls distortion: Formation of helices of polyketone and polyisocyanide - Cui, C.-X.; Kertesz, M. (Elsevier)
A new type of Peierls-like distortion, the formation of a helix due to the existence of partially filled crossing bands, is reported for polyketone and polyisocyanide. The torsional potential curves, optimized geometries, band structures and phonon dispersion curves are derived. A comparison with the well-known Peierls-distorted all-trans polyacetylene indicates close similarity between the two types of Peierls distortions.
