Abstract
Oligopyrroles with increasing chain length and polypyrroles were recen tly synthesized with new chemical methods. In this paper, we analyze t heir infrared and Raman spectra. The spectra can be nicely interpreted in terms of recent theoretical concepts of vibrational dynamics of po lyconjugated systems. The spectra thus become a tool for deriving info rmation on the structure of these materials.
