采用反射吸收光谱（FTIRAs）和KBr透射红外光谱（FTIR）对电化学合成的聚吡咯薄膜进行了研究。 在RAS光谱中，在3400 cm-1处观察到NH伸缩模式，而在KBr透射光谱中没有观察到NH伸缩模式。 由于RAS方法检测到垂直模式和KBr透射光谱是由于横向模式，电化学合成的聚吡咯具有更高的顺序结构，使NH键的取向与膜平面平行，以及在氮位点的氢缺乏的影响。 观察到的聚合物IR谱图的环伸缩带和CH面内和面外模式与单体的不同，反映了α-α '共轭聚合物结构。
A Fourier transform infrared (FTIR) spectroscopy study of an electrochemically synthesized polypyrrole film is conducted by means of reflection absorption spectroscopy (FTIR RAS) and the FTIR KBr disk transmission method. In the RAS spectrum, the NH stretching mode is observed at 3400 cm-1, while no NH stretching mode is observed in the KBr transmission spectrum. Since the RAS method detects the vertical mode and the KBr transmission spectrum is due to the lateral mode, the electrochemically synthesized polypyrrole has higher order structure so that the orientation of the NH bond is parallel to the film plane together with the effect of hydrogen deficiency at the nitrogen site. The observed polymer IR spectrum profile for the ring-stretching band and the CH in-plane and out-of-plane modes is different from that of the monomer, reflecting the alpha-alpha' conjugated polymer structure.
