    Frequency dependence of the memory and force autocorrelation functions and its use in separating homogeneous and inhomogeneous broadening. Application to methyl iodide (1988)
    Chichester [u.a.] : Wiley-Blackwell
    Journal of Raman Spectroscopy 19 (1988), S. 289-295

    Notes: Spontaneous Raman spectra of the n̈3 band of methyl iodide were recorded at 1 bar and 2 kbar at ambient temperature. These spectra yielded vibrational, memory and frequency autocorrelation functions. The frequency dependence of the memory function was shown to be identical with that of the force autocorrelation function. An autoregressive analysis of the memory function allowed the separation of the homogeneous and inhomogeneous second moments. This separation of second moments was compared with a theoretical separation of the homogeneous and inhomogeneous bandwidths.

    13C substituent-induced chemical shifts in 1-amino-4-phenyl- and 4-phenyl-1H-1,2,3-triazoles (1986)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 24 (1986), S. 53-54 
    Details
    ISSN: 0749-1581
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Chemistry and Pharmacology
    Notes: The 13C NMR spectra of several 3′- and 4′-substituted 4-phenyl-1,2,3-triazoles have been recorded, and the observed chemical shifts analysed in terms of (i) the influence of this heteroaromatic system on the phenyl carbons and (ii) the transmission of the electronic effects of the meta and para substituents on the phenyl ring to the triazole carbon atoms.

    Vibrational dephasing in liquid germane (1988)
    Chichester [u.a.] : Wiley-Blackwell
    Journal of Raman Spectroscopy 19 (1988), S. 277-279

    Notes: Raman spectra are reported for the n̈1 bands of germane and germane-d3. Fourier transformation of the band shapes provided vibrational autocorrelation functions. These functions were modeled by a memory-function procedure. Evidence for resonant vibrational energy transfer and higher order cumulant-expansion terms was found in an isotopic-dilution study.

    Vibrational dephasing of arsine in the liquid and plastic crystalline states (1988)
    Chichester [u.a.] : Wiley-Blackwell
    Journal of Raman Spectroscopy 19 (1988), S. 467-469 
    Details
    ISSN: 0377-0486

    Topics: Chemistry and Pharmacology , Physics
    Notes: Raman spectra of the ν1 bands of AsH3 have been obtained for the liquid state and for phase I of the solid state. It is shown that phase I is a plastic crystalline phase. A modeling procedure applied to the vibrational autocorrelation function shows that the modulation of the vibrational frequency is fast and that the vibrational dephasing is probably caused by the rotations. Evidence for a ν1-ν3 Coriolis-coupling effect is also presented.

    Vibrational dephasing of the ν3 mode of liquid allene (1986)
    Chichester [u.a.] : Wiley-Blackwell
    Journal of Raman Spectroscopy 17 (1986), S. 477-480

    Topics: Chemistry and Pharmacology , Physics
    Notes: The Raman spectrum of the ν3 mode of allene has been studied as a function of temperature throughout the temperature range of the liquid. Analysis of the spectral band shape shows that the vibrational dephasing is a fast-modulation process. Evidence is presented for a vibrational-rotational coupling involving the tumbling reorientation of the molecule. Dilution studies in GeH4 indicated significant resonant vibrational energy transfer.

    Raman spectrum of Sr0.61Ba0.39Nb2O6 (1991)

    Notes: The Raman spectra of a single crystal of strontium barium niobate were recorded in the temperature range-193 to 140°C. The configurations studied were X(ZZ)Y, X(YZ)Y, X(YX)Y, Z(XX)Y, Z(YZ)Y and Z(XZ)Y. The behavior of integrated reduced intensities, band widths and band centers with temperature indicated that the ferro-electric transition temperature was near 65°C. The Raman data were not consistent with a classical Landau transition. Disorder-induced first-order spectra were observed and attributed to the disordered nature of the crystal Evidence was found for a possible phase transition near 120°C.
