The ENDOR spectra for the Feast - type polyacetylene was seen to be
temperature - independent up to 200 K and the half width of the soliton was found
to correspond to 12 CH units ( i . e . total width = 25 units ) . The authors believe

Of particular interest is the influence of the bond that links the monomer units . In
the case of polypyrrole , the optical gap is theoretically expected to decrease from
3 . 2 eV to 2 . 6 eV if this bond length is reduced from 1 . 49 Å to 1 . 4 Å [ 4 . 19 ] .
