Polaron and Soliton Lattices Within One-Particle Models of Conducting Polymers with a Degenerate Grothe lattice and/or various electron-hole symmetry breaking terms in the π-electronic part. In the case of PY, for strong double-well type an- harmonicity and arbitrary dopant concentration a polaron lattice formed by singly charged polarons is found to be energetically more favorable than lattices f

Excitons in Chains of Thiophene Rings term produces a large excitonic splitting in any chain conformation. Depending on inter-ring rotation angles and chain size, transitions are shifted from UV range up to the red. Computed spectra agree well with experiments for films and solutions of oligomers, and solutions of the polymer. These re

Electronic Properties of Nonconjugated Polymers: 1,4-Polybutadiene and 1,4-Polyisoprenehe polymers with skewed conformations possess a width for the highest occupied valence band in the range 0.79-0.93 eV. Holes in that band should therefore present a significant intrachain mobility. The solid-state ionization potentials are found to be too large to allow for oxidation by iodine and f
