摘要：

The vibrational features of conducting polymers have proved to be very suitable to characterize the conducting state, since they are directly related to the electronic configuration. We present a vibrational study(experimental measurements and dynamical calculations) of emeraldine salt (ES), the conducting form of polyaniline. In addition, similar analysis is proposed on some oligomers and their corresponding radical forms, chosen as model compounds of ES for our calculations. These results are interpreted in terms of valence-force-fields, characteristic of the different charged defects.
