We present a complete study of the conductive form of the polyaniline emeraldine salt. The experimental spectra of emeraldine salt doped in the classical way and also by the action of camphorsulfonic acid– m ‐cresol are presented. Vibrational calculations on emeraldine salt are presented, considering the non‐planar geometry of the polymer. A study of the influence of the torsion angle between cycles is proposed. Finally, a complete assignment of the Raman vibrational modes of emeraldine salt is discussed. Copyright © 2000 John Wiley & Sons, Ltd.
