Abstract
The low frequency infrared speetra (800 $33 cm^{-1}$) of solid films of $Li^{-}$, $Na^{+}$, $K^{+}$ and $Cs^{-}$ ionomers of ethylene-methacrylic acid copolymers have been examined. These spectra contain cation dependent bands, which are attributed to the motion of the cation in the field of the carboxyl groups within the ionic domains that are known to be formed, besides the perturbed spectrum of the unneutralized copolymer. These results are interpreted in relation to the far-infrared and Raman bands arising from interionic motion of alkali metal salts in non-aqucous solvents.
