The infrared spectra of pyrene and pyrenehyphen;d10in the crystalline state and in solution of various solvents were measured between 4000 and 400 cmhyphen;1.Spectra in polarized light with the electric vector of the incident light vibrating in theabcrystal plane were obtained from both single crystals and oriented polycrystalline samples. Spectra in polarized light with the electric vector in theaccrystal plane were also obtained from oriented films. The comparison of the experimental dichroism with the predictions based on the knowledge of the crystal structure allowed an almost complete assignment of the fundamental modes of vibrations active in the ir spectrum.
