    Notes: The Fourier-transform (FT) Raman spectra of genuine samples of scrimshaw are reported and compared with those of fake scrimshaw, ivory and human milk tooth. The major spectral features in all systems examined were assigned. The application of the FT-Raman technique to the non-destructive diagnostic identification of scrimshaw and simulated scrimshaw artefacts is demonstrated.

    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 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 application of Raman spectroscopy to polymers and polymerization processes is surveyed and the advent of recent advances in instrumental techniques to polymer analysis is highlighted. Some of the problems of the more widely-used infrared spectroscopic methods, for example in microstructural analysis of polydienes and copolymers, are discussed and the advantages of the Raman spectroscopic technique are explained. The use of near-infrared excitation and Fourier-transform Raman instrumentation for process monitoring and polymer composite studies is discussed. Raman microscopic and waveguide spectroscopic studies of small samples and polymer coatings on substrates are considered. Other applications are mentioned in the areas of polymer orientation, surface-enhanced Raman scattering, conducting polymers, biopolymers and time-resolved studies.

    Notes: Fourier transform (FT) Raman spectra of the cell walls of three species of fungi are reported for the first time, namely (i) Agaricus bisporus, a fruiting bud, (ii) Mortierella genus and (iii) Mucor genus. Some molecular assignments are proposed for the major vibrational features and attributed to chitin, N-acetylglucosamine and (R)-glucan. Preliminary studies indicate that it is possible to use FT-Raman spectroscopy to discriminate between different mixed species in culture media.

    Fourier transform Raman spectroscopic study of lithium perchlorate solutions in acrylonitrile (1995)

    Notes: Lithium perchlorate solutions in acrylonitrile (propenenitrile), in a range of concentration between 1 and 6 molal, were studied by using Fourier transform Raman spectroscopy. The new band in the v(CN) region proceeding from the bound species Li+… (acrylonitrile)n and the modifications in the C - C stretching band were studied in detail by means of deconvolution and band-fitting procedures. An average solvation number of ca. 2.3 was obtained without any correction for the ion pairing. The data obtained in the analysis of the perchlorate anion v1 (symmetric stretch) band allow us to quantify the concentration of the different species (free perchlorate, solvent-separated ion pairs and contact ion pairs) present, and to obtain a more realistic solvation number for the lithium ion in acrylonitrile solutions. This solvation number was estimated at 3.0 ± 0.1.

    Notes: The pressure-broadening coefficients for the self-broadened S0(0), S0(1) and S0(2) pure rotational Raman lines of hydrogen and the S0(0) to S0(4) lines of deuterium were determined experimentally over the pressure range 1-100 bar and the temperature range 90-375 K. Broadening coefficients were also determined for the same lines in hydrogen and deuterium perturbed by helium, argon, oxygen, nitrogen, carbon monoxide and hydrogen chloride over the pressure range 2-100 bar, with a partial pressure of the host gas of 1 bar and a temperature of 293 K. In addition, the S0(0) pure rotational line of deuterium broadened by carbon monoxide and nitrogen was studied over the same pressure range and a temperature range of 100-293 K. The results are discussed and compared with those of previous studies in the literature.

    Notes: Raman spectra of the α-, β-, γ- and smectic polymorphs of isotactic polypropylene were recorded at 298 and 16.5 K. At 298 K the spectra of the polymorphs were very similar except in the antisymmetric C—H stretching region. However, at 16 K the Raman spectra of the polymorphs show different features in several wavenumber shift regions. Comparisons are made with infrared spectra recorded at 298 and 100 K and interpretations are made on the basis of non-equivalent sites in the monoclinic unit cells.

    Notes: The dissociation constants for an acetonitrile-zinc complex, (CH3CN)Zn2+, were measured in aqueous solutions containing zinc salts (40-80%, w/w) and acetonitrile by Raman spectroscopy. Quantitative measurements of the intensity of the free and complexed ν(CN) Raman bands at 2264 and 2320 cm-1, respectively, were used to determine the average enthalpy and entropy of the complex dissociation to free acetonitrile in the temperature range 293-343 K for a 70% (w/w) solution of zinc chloride (0.052 mol) in an aqueous solution containing acetonitrile (0.024 mol); δH° and δS° values of 8.4 ± 0.5 kJ mol-1, respectively, were determined.

    Notes: The construction of a remote Raman microscope system with a variable microscope-to-spectrometer distance of up to 3 m is described. Oxidative surface corrosion products on zirconium alloy and stainless-steel nuclear fuel claddings for pressurized water and advanced gas cooled reactor systems produced under various conditions were studied and the potential of the technique for in situ analysis is discussed. Under the conditions studied experimentally, the major corrosion products are found to be α-ZrO2 and α-Fe2O3 for the zirconium alloy and stainless-steel claddings, respectively.
