Experimental IR spectra of perfluoropolyethers show many features which cannot be interpreted by means of simple correlations commonly used for band assignments. First-principles calculations on suitable molecular model should be used to this aim and reveal the existence of peculiar intra and intermolecular interactions which are responsible for the modulation of both the structural and spectroscopic properties of these polymers.

Abstract
Experimental IR spectra of perfluoropolyethers show many features which cannot be interpreted by means of simple correlations commonly used for band assignments. First-principles calculations on suitable molecular model should be used to this aim and reveal the existence of peculiar intra and intermolecular interactions which are responsible for the modulation of both the structural and spectroscopic properties of these polymers.File in questo prodotto:
