Far-infrared transmittance spectra (200-30 cm-1) of the hydrogen bond in cyclic dimers of 4-n-heptyl-, octyl-and nonyloxybenzoi c acids are observed and investigated. The spectral bands at 42, 63, 68 and 82 cm-a are assigned to the four deformation vibrations: twisting, bending (in and out of the di
