It can be shown that such a system cannot exist as a one - dimensional metal
with a half - filled band , but rather as an insulator with a gap forming at the Fermi
level . The reason for this is either the Peierls instability , or electron correlation ,
or ...

Increasing disorder leads to the formation of band tails and a gradual filling of the
gap with density of states , but it cannot explain the sudden appearance and the ...

Therefore , an assumed helicity of the pyrrole polymer might be expected to
reduce the band gap and rotational disorder to give rise to a broadening of the
optical absorption feature at the band gap . In the case of cis - polyacetylene ,
helix ...
