      The review indicates that the assignment of D and G bands, and its consequent deconvolution cannot be blindly applied to all amorphous carbons and that this is especially true for coals of different ranks. Therefore, the correlations between band width and intensities and graphitization, carbonation, rank/order, char structure and reactivity of coke are not consistent. Preliminary investigations indicated promising results for the characterization of inorganic matter and minerals in coal.

      Significant improvements in both signal sensitivity and imaging speed of interferometric multiplex coherent anti-Stokes Raman scattering microscopy are achieved by adopting an apodization function and the crop mode operation of charge-coupled device. A speed of 3 s per a vibrational hyperspectral image of 100 × 100 pixel is demonstrated. Superior chemical selectivity is also demonstrated with polymer and oil samples.

    2. Surface-enhanced Raman scattering study of human serum on PVA[BOND]Ag nanofilm prepared by using electrostatic self-assembly (pages 137–144)

      Enhanced Raman scattering (ERS) for bulk Si and surface brilliant cresyl blue molecules is investigated by individual polystyrene microspheres placed on top of the samples. A strong ERS effect is observed, which depends both on the microsphere size and the numerical aperture of the collection lens.

    4. Interfacial electronic properties of Au[BOND]GaAs interfaces studied by photomodulation Raman spectroscopy (pump–probe technique) (pages 149–152)

      T. A. El-Brolossy, S. Negm and H. Talaat

      Version of Record online: 9 MAR 2010 | DOI: 10.1002/jrs.2635

      Photomodulation Raman spectroscopy (PM-RS) was employed to investigate the interfacial properties of Au: n-type GaAs interfaces, using the forbidden longitudinal optical (LO) phonon scattering as a probe. The interfacial minority carrier trap lifetime was determined through dynamical measurements of the PM-RS intensity as shown in the Figure.

    5. Ultraviolet Raman scattering in ZnO nanowires: quasimode mixing and temperature effects (pages 153–159)

      The resonant Raman spectrum of wurtzite ZnO nanowires (NWs) has been investigated in terms of laser-induced heating effects and the quasimode nature of the longitudinal Raman feature (QLO). We show that light refraction, together with the orientation-dependent cross-section of the NWs for the incoming light, counterbalances the quasimode mixing effects in an ensemble of randomly aligned NWs, giving rise to LO bands that are barely redshifted relative to the pure E1(LO) mode.

    6. Depth-resolved in vivo micro-Raman spectroscopy of a murine skin tumor model reveals cancer-specific spectral biomarkers (pages 160–166)

      A confocal-Raman spectroscopy system was developed for differentiating tumor from normal skin in vivo. Measurements on 24 mice with squamous cell carcinoma revealed different spectral patterns at different depths and between normal and tumor-bearing skin sites. A peak at 899 cm−1, possibly from proline or fatty acids, and one with higher intensity in the 1325–1330 cm−1 range, assigned to nucleic acids, were correlated with the presence of tumors, which can potentially be used as biomarkers for skin cancer detection.

      The effect of spectral resolution on the FT-Raman spectra of PAHs and beta-carotene mixtures has been investigated. While no significant changes were observed between the FT-Raman spectra collected at 4 and 6 cm−1 resolution, the spectra collected at 8, 16 and 32 cm−1 resolution have a significantly different spectral appearance. The results will provide useful information to build up a database of simulated systems which can be used for the remote detection of possible life signatures in planetary exploration.

    10. Raman excitation of (+)-(R)-methyloxirane and its origin of optical activity via bond polarizabilities (pages 186–191)

      The bond polarizabilities of chiral (+)-(R)-methyloxirane from its Raman intensities were studied. It is shown that the coupling of the electric dipole induced by the excited charges in the methine bond and the magnetic moment vibrationally induced by the electric current in the triangular skeleton is the key factor leading to its significant Raman chirality.

      We have carried out a temperature-dependent polarized Raman study of PrFeO3 thin films grown on LaAlO3 by pulsed-laser deposition from 80 to 300 K. Many interesting features were observed and are discussed. Especially, the mode at 624 cm−1 that was considered to be due to impurities is proved otherwise and its assignment to a two-phonon mode is supported.

    14. Raman and IR spectra of K4Nb6O17and K4Nb6O17·3H2O single crystals (pages 209–213)

      M. Ma̧czka, M. Ptak, A. Majchrowski and J. Hanuza

      Version of Record online: 21 APR 2010 | DOI: 10.1002/jrs.2668

      Thumbnail image of graphical abstract

      Raman and IR spectra of K4Nb6O17 and K4Nb6O17· 3H2O single crystals were measured. The studies revealed that intercalation of water molecules leads to shifts, broadening and changes in intensity of some bands. These changes were attributed to the slight changes in the bond lengths and angles, interactions of the water molecules with K atoms and structural disorder introduced by the intercalated water molecules.

    15. Raman spectroscopy of hydrogen-arsenate group (AsO3OH) in solid-state compounds: cobalt mineral phase burgessite Co2(H2O)4[AsO3OH]2·H2O (pages 214–218)

      The Raman spectrum of mineral klebelsbergite Sb4O4(OH)2(SO4) was studied and related to the structure of the mineral. Based upon Raman spectroscopy, it is proposed that the two sulfate anions are distorted to different extents in the klebelsbergite structure.

    17. Effect of pH on the uptake of arsenate and vanadate by hydrotalcites in alkaline solutions: a Raman spectroscopic study (pages 224–229)

      Sara J. Palmer and Ray L. Frost

      Version of Record online: 6 MAY 2010 | DOI: 10.1002/jrs.2680

      Thumbnail image of graphical abstract

      Raman spectroscopy and inductively coupled plasma optical emission spectroscopy shows a reduction in the concentration of arsenate and vanadate anions that are removed in extremely alkaline solutions. Hydrotalcites containing arsenate and vanadate are stable in solutions up to pH 10. Exposure of these hydrotalcites to higher pH values results in the removal of large percentages of arsenate and vanadate from the hydrotalcite interlayer.

    18. Vibrational spectroscopy and DFT calculations of N,N′-dicyclohexylcarbodiimide (pages 230–238)

      In situ micro-Raman measurements were carried out on as-prepared γ-Fe2O3 nano- particles of about 4 nm in size as a function of laser power and on annealed γ-Fe2O3 particles. A baseline profile analysis has clearly evidenced that the phase transition from maghemite into hematite was caused by local heating due to laser irradiation.
