ABSTRACT
The transitions near the middle oxidation peak of polyaniline were studied by resonance Raman spectroelectrochemistry. Localization polarons was observed in potential region between first and peaks connected with coupling into pairs – specific bands separated polarons, emeraldine states general. In addition, a connection cyclic voltammetry hydroquinone/benzoquinone defect redox transition confirmed. These findings allow more precise determination oxidation, protonation, degradation level spectroscopy. Copyright © 2017 John Wiley & Sons, Ltd.
