✦ Synopsis

The equihbrium between monomericand associated forms of pertIuorocarboxylic acids in carbon tetrachloride solution has been studied by Fourier transform infrared spectrometry. It was found that the overlap of the carbonyl stretching bands of the monomer and associated forms was too great to permit the nature of the associated form to be determined accurately. After conversion of the solvent-compensated absorbance spectra to their second derivative and measurement of the height of the secondary maxima of the overlapping bands, the associated species was confirmed to be the dimer.
