Electronic transport in individual polyacetylene chains is studied.

Microwave emulation experiments and tight-binding calculations agree well.

In long chains a band-gap opens due the dimerization of the chain.

In short chains edge atoms cause strong resonance peaks in the center of the band-gap.
