    Densimeter detector in gel permeation chromatography of copolymers (1982)
    New York : Wiley-Blackwell

    Notes: A commercially available densimeter with a vibrating stainless steel tube was used as a detector in the GPC analysis of styrene/methyl methacrylate copolymers under normal GPC operational conditions. The densimeter was thermostated to ±0.001°C and sample injection concentrations were 4.0 mg/mL. The copolymer samples were polydisperse in molecular weight but uniform in composition. A refractive index detector and the densimeter detector produced comparable estimates of the parameters of the molecular weight distributions. The densimeter is less sensitive to the effects of variations in copolymer composition than differential refractive index or ultraviolet detectors. The only serious drawback to the densimeter is a relative lack of sensitivity. Variations in composition of styrene/methyl methacrylate copolymers over a fairly wide range have no signficant effect on the relation between gel permeation chromatographic elution volume and copolymer molecular weight. In general, however, conventional means of summarizing these data are not applicable to compositionally heterogeneous mixtures. Instrumental and data-handling solutions to this problem are discussed.

    Raman spectral studies of cis-2-butene-benzene mixtures (1974)
    Chichester [u.a.] : Wiley-Blackwell
    Journal of Raman Spectroscopy 2 (1974), S. 593-607 
    Details
    ISSN: 0377-0486
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Chemistry and Pharmacology , Physics
    Notes: Raman spectra of neat liquid cis-2-butene and cis-2-butene-benzene mixtures, covering the accessible composition range at 20°C and atomospheric pressure, have been obtained. Parameters of the benzene bands at 605.6, 1178 and 991.6 cm-1 and cis-2-butene bands at 395.5, 871.5 and 1660 cm-1 are reported. Changes in the parameters as a function of concentration are interpreted in terms of a weak dipole-induced dipole interaction and the consequent effect on rotational motions and resonance energy transfer.
