Measurements of dielectric permittivity and electric conductance are presented for mixtures of carboxylic acids - formic, trifluoroacetic, acetic and propionic - and non-polar liquids. For the dielectric and associative behavior of carboxylic acids a knowledge of the cis-trans conformational equilibria of the monomeric acid molecules seems to be essential. Therefore the cis and trans conformations of these molecules have been calculated by the CNDO/2 and PCILO methods. Appreciable rotational barriers for their interconversion have been obtained.
