Abstract:
Far-infrared absorption spectra for liquid acetone, methylene chloride, acetonitrile, methyl
iodide, and their dilute solutions in cyclohexane at 20?C are measured by molecular laser
spectrometer. Measurements of dielectric loss of polar liquids and solutions in the frequency
range 2-300 GHz are made using a number of different techniques. These two sets of
measurements are combined with those made using a Fourier transform spectrometer in order
to cover the frequency range up to 250 cm -I and total integrated absorption intensities are
calculated. It is shown that the discrepancy between experimental integrated absorption and the
theoretical results given by Gordon's sum rule with the Polo-Wilson internal field factor can be
explained in the context of Bossis' theory. This theory gives a better agreement with the experimental
integrated absorption intensity for these liquids.
