Abstract
The optical spectra of polyacetylene doped with iodine (p type) or sodium (n type) are investigated in the infrared and visible region. The change of spectra with doping is measured quantitatively. Model structures of the charged soliton lattice are suggested for p and n type chains of the highest doping levels. The reflection spectra of (CHIy)x and (CDIy)x for heavy doped films are measured and analyzed by five transitions existing in 0 - 24000 cm−1 region. By lowering the temperature to 30 K, the gapless transition is disappeared presumably because the lattice with the charged soliton is frozen.Keywords
