    Surface tensions of liquid polyisobutylenes (1968)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 12 (1968), S. 2213-2224 
    Details
    ISSN: 0021-8995
    Keywords: Chemistry ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: Measurements of surface tensions were carried out in the temperature range 25-120°C on seven different liquid polyisobutylenes with molecular weights ranging from 100 to 80,000. Relationships between the surface tenstion of polyisobutylene and other properties, such as the parachor, cohesive-energy density, and molecular weight are discussed.

    The pure rotational Raman spectrum of sulphur trioxide (1978)
    Chichester [u.a.] : Wiley-Blackwell
    Journal of Raman Spectroscopy 7 (1978), S. 154-157 
    Details

    Notes: The pure rotational Raman spectrum of sulphur trioxide in the vapour phase at 333K has been obtained and analysed for the first time. The following rotational constants and bond length were determined: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{l} B_{\rm 0} {\rm = 0}.348\,57 \pm {\rm 0}{\rm .000\,03 cm}^{ - 1} \\ 10^{\rm 7} D_J {\rm = 2}{\rm .68} \pm {\rm 0}{\rm .07 cm}^{ - 1} \\ r_{\rm 0} {\rm = 141}{\rm .98} \pm {\rm 0}{\rm .02 pm} \\ \end{array} $$\end{document} This r0 value agrees to within the sum of one standard deviation of the experimental errors with the value obtained from an analysis of the vibration-rotational infrared spectrum of the 2ν3 band.

    Notes: The pure rotational Raman spectrum of selenium trioxide monomer in the vapour phase at 410 K has been obtained and analysed for the first time. The following rotational constants and bond lengths were obtained: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{l} B_{\rm 0} {\rm = 0}{\rm .246\,60} \pm {\rm 0}{\rm .000\,05 cm}^{ - 1} \\ 10^{\rm 8} D_J {\rm = 3}{\rm .9} \pm {\rm 0}{\rm .04 cm}^{ - 1} \\ r_{\rm 0} {\rm = 168}{\rm .78} \pm {\rm 0}{\rm .02 pm} \\ \end{array} $$\end{document} This is the first spectroscopic determination of r0 in SeO3. The precision of r0 is significantly greater than the value of ra = 169±1 pm obtained from an earlier electron diffraction study.

    Notes: The pure rotational and vibration-rotational Raman spectra of the hydrogen species 1H3H and 2H3H have been recorded and analysed. The following rotational constants, vibration-rotational constants and bond lengths were obtained: The re values are compared with those of 1H2, 1H2H, 2H2 and 3H2 and a weighted mean re value for the hydrogen molecule was calculated.
