Abstract
We have studied the FT-IR and FT-Raman spectra of a neutral thiophene-based oligomer in relation to the effective conjugation length of the pi-electro ns. The compound has a well-barrier-well structure, where the well parts ar e two bithienyl end-moieties and the barrier part is a vinylene fragment wi th a larger energy gap. Characteristic features are correlated with vibrati onal data of one-dimensional unsubstituted alpha-oligothiophenes and alpha, alpha-dimethyl end-capped oligothiophenes.
