The table shows the results obtained: Ae'/c is the so-called dielectric increment per mole and h~"/c is the absorption coefficient increment per mole; e' and &" being the real and the imaginary parts of the dielectric constant ~= ~' -i~".The increments d ~0/c of the static dielectric constant per mole were taken from the literature. 2 s The table shows also the relaxation
