This paper reviews the possibilities to get information about the molecular and electronic structure of various conjugated materials like conducting polymers, carbynes and fullerenes by resonance Raman scattering. Examples are given for the investigation of defects and order in the polymers by using the dependence of the Raman line position on the conjugation length. Resonance Raman spectra of the linear carbon allotrope carbyne prepared by reductive electrochemical carbonization of teflon are presented. The strongest mode at around 2000 cm1 is discussed in terms of the C≡C stretching mode of polyyne. Then the strong resemblance and also some differences between the pentagonal pinch mode of C60 and the CC stretching mode of polymers are shown and changes with doping in the vibrational spectrum of C60 are discussed. The usefulness of Raman scattering for investigating the doping process of C60 is demonstrated by the discussion of the new alkalifulleride phase A1C60. Finally, Raman spectra of both single-wall and multi-shell carbon nanotubes are analyzed.
