    ISSN: 1057-9257
    Keywords: Polypyrrole ; Conducting polymer composites ; Electrical modelling ; Microwaves ; Radar-absorbing material ; Chemistry ; Polymer and Materials Science

    Topics: Electrical Engineering, Measurement and Control Technology , Physics
    Notes: The microwave absorption and reflection characteristics of composites of polypyrrole with paper, cotton cloth and polyester fabrics have been evaluated. Refiectivity measurements in the range 2-18 GHz and plane wave modelling have revealed impedance charateristics with a common transition rgion. Relationships between substrate material, polymer loading and electrical performacne have been explored. Polarisation characteristics have alos been measured. The electrical model has been successful in predicting the performance of both Salisbury screen and Jaumann multilayer designs of radar-absorbing material.

    Raman and infrared spectra of the solid chlorofluorocarbons. I - chlorotrifluoromethane (1990)
    Chichester [u.a.] : Wiley-Blackwell
    Journal of Raman Spectroscopy 21 (1990), S. 693-697

    Topics: Chemistry and Pharmacology , Physics
    Notes: Raman and infrared spectra of solid chlorotrifluoromethane have been recorded in both the internal and lattice mode regions at temperatures between 20 K and its melting point. The spectra are compared to the predictions of a group theoretical analysis based on the known molecular and unit cell symmetries. The absence of a centre of inversion is confirmed. Plausible assignments of all main spectroscopic features are presented.

    Notes: Raman and infrared spectra of solid dichlorodifluoromethane were recorded in both the internal and lattice mode regions at temperatures between 20 and 80 K. The lattice spectra suggest that the unit cell is small and noncentrosymmetric, and a bimolecular tetragonal cell with factor group C4 is compatible with the observed results. Plausible assignments of all main spectroscopic features are presented, and splittings of internal modes are interpreted in terms of isotopic, crystal, field, Fermi resonance and LO-TO effects.

    Notes: Raman and infrared spectra of crystalline trichlorofluoromethane at temperatures between 20 and 80 K were recorded in both the lattice and internal mode regions. The lattice spectra are shown to be compatible with a non-centrosymmetric tetragonal unit cell containing four molecules on mirror plane sites, and plausible assignments are proposed. The internal mode splittings are interpreted in terms of isotopic, crystal field, Fermi resonance and LO-TO effects.

    Notes: Raman and infrared spectra of solid dichlorofluoromethane were recorded in both the internal and lattice mode regions at 20 and 80 K. The lattice spectra are consistent with a non-centrosymmetric unit cell containing at least four molecules. All nine internal modes are observed, and their multiple components are interpreted in terms of crystal field effects and isotopic splittings.

    Notes: Raman and infrared spectra of solid H2Se at temperatures between 85 and 20 K are reported and interpreted. The broad peaks observed in the spectra of phase II are characteristic of an orientationally disordered crystal, whereas the multiple components of the internal modes and rich lattice spectra found for phase III are indicative of an ordered structure. The unit cell for this phase is probably centrosymmetric and contains at least four molecules. Plausible assignments for all observed spectroscopic features are proposed.

    Raman study of a phase transition in solid chlorodifluoromethane (1992)

    Notes: Raman spectra of solid chlorodifluoromethane at temperatures between 20 and 80 K in both the lattice and internal mode regions are reported. Evidence of a solid-state phase transition at 60 ± 5 K is presented. In both phases, the multiplet structure of the internal fundamentals is shown to originate from crystal field rather than isotopic effects for most modes, which indicates that both phases are ordered with fairly large unit cells and that the transition is therefore of a displacive type.

    Notes: Raman and infrared spectra of soiid dibromodifluoromethane are reported for both the lattice and internal mode regions at temperatures between 12 K and the melting point. No evidence was found for a solid-state phase transition. Plausible assignments of all observed spectroscopic features are suggested. The spectra are compatible with a non-centrosymmetric unit cell containing four molecules.

    Notes: Vibrational spectra of solid tribromofluoromethane at temperatures between 12 K and the melting point were obtained using Raman and infrared techniques, with special emphasis on the lattice modes. No evidence for a solid-state phase transition was found. Lattice peaks are tentatively assigned on the basis of geometrical and intensity arguments. It is shown that the spectra are compatible with a non-centrosymmetric unit cell containing four molecules.

    Notes: Raman and infrared spectra of solid CH2CIF (Freon 31) were recorded in both the lattice and internal mode regions for samples at temperatures between 12 and 125 K. No evidence of any solid-state phase transition was found, but some thin-film samples deposited at low temperatures appear to exist in a metastable phase. Spectra of the stable phase are compatible with a non-centrosymmetric unit cell containing four molecules. Lattice peaks are assigned on the basis of geometrical and intensity arguments.
