Abstract

In this paper Raman and infrared spectra of polyaniline 1A, acid-treated 1A (1S), oxygen-treated 1A left bracket 1A(O//2) right bracket , and doped 1A are studied. Assignments of vibrational spectra are made referring to the data of **1**5N-substituted and C-deuterated polyanilines, N,N prime -diphenyl-1,4-benzenediamine, and its derivatives. Key bands that are useful in determining the structures of various forms are elucidated and the relation between vibrational spectra, structures, and electrical properties is discussed. It is found that semiquinone radical cations of IP units exist only in the conducting forms of polyaniline, 2S and doped 1A, indicating that semiquinone radical cations play an important role in electrical conduction in polyaniline.
