Oligopyrroles with increasing chain length and polypyrroles were recently synthesized with new chemical methods. In this paper, we analyze their infrared and Raman spectra. The spectra can be nicely interpreted in terms of recent theoretical concepts of vibrational dynamics of polyconjugated systems. The spectra thus become a tool for deriving information on the structure of these materials.
