Abstract
The IR absorption spectra of 4-cyano-4',-p-alkoxybiphenyls were invest igated experimentally (in the range 100-3200 cm-1 at 100-400 K), and t hey were interpreted on the basis of a calculation of the frequencies, forms and intensities of the normal vibrations of various conformers of the propyloxycyanobiphenyl molecule. Temperature and phase changes in the parameters of the IR spectrum are explained by a change in the conformational composition and intermolecular interactions in the inve stigated liquid crystals.
