Abstract
The dielectric spectra of binary liquid mixtures of the following alco hols with N,N-dimethylformamide (DMFA) have been measured between 5 MH z and 72 GHz at 20 degrees C:1-Hexanol, 1,2-hexanediol and 1,4-butaned iol. The analysis of the spectra, which is particularly aimed at infor mation on hetero-association, gives evidence for the formation of mixe d aggregations, indicated by a minimum in the 'free' DMFA relaxation c ontribution at a mixture ratio of about 1:1 for hexanol/DMFA and about 1:2 in case of the dihydric alcohol/DMFA systems.
