Abstract

Fourier transform infrared (FTIR) measurements of AsF5 doped (CH)x with dopant concentrations which vary over three orders of magnitude have been obtained in both the mid (4000-400 cm-1) and far (400-15 cm-1) infrared. The bandwidths of the strong bands characteristic of the doped polymer have been observed to be invariant with dopant concentration. However, the frequency positions of these new IR bands are found to be a sensitive function of the dopant level. In the far infrared, no evidence of the predicted soliton pinning mode was found for any of the dopant concentrations studied. The consequence of these results, in view of current theoretical models of the polymer-dopant interaction, is discussed. © 1982 American Institute of Physics.
