    The reaction γ +d → π+ + π− +p + n between 570 and 850 MeV andΔ ++ Δ − production (1992)

    Notizen: Abstract The reaction γ+d → π++π− +p + n has been measured in a kinematically complete way at incident photon energies from 570 to 850 MeV in steps of 40 MeV. From detailed comparison of measured data with results of event simulations, it is concluded that three different mechanisms, the quasi-free, double-delta and phase space productions, contribute to the reaction. Each of the cross sections corresponding to these mechanisms is determined separately.

    Notizen: High-pressure Raman spectra of liquid and solid ethanol were measured at pressures up to 17 GPa and 300 K in a gasketed diamond anvil cell. The frequencies of in-phase and out-of-phase O—H stretching vibrations which characterize the hydrogen bond along the zig-zag chain decrease with increasing pressure with slopes(dν/dP) of -14.3 and -12.4 cm-1 GPa-1, and they overlap with the CH stretching mode at about 11 and 17 GPa, respectively. No solid-solid phase transition was observed at pressures up to 17 GPa.

    High-pressure Raman study of methyl iodide (CH3I and CD3I) up to 12 GPa (1992)

    Notizen: High-pressure Raman spectra of liquid and crystalline CH3I and CD3I were measured up to 12 GPa at 300 K in a gasketed diamond-anvil cell. The liquid-solid phase transition pressures were determined as 0.9 GPa for CH3I and 0.8 GPa for CD3I. For both CH3I and CD3I, two translational and two librational modes were observed in the pressure-induced solid phase. The frequencies of the librational modes increased rapidly with increasing pressure. The frequency of the intense ν3 mode also increased rapidly with pressure. Splitting of fundamental modes was found in the solid phase, and this behaviour is discussed in terms of crystal field effects.

    High-pressure Raman study of liquid and solid thiophene up to 100 kbar at 300 K (1988)

    Notizen: High-pressure Raman spectra of liquid and solid thiophene C4H4S have been measured up to 100 kbar at 300 K in a gasketed diamond anvil cell. The pressure dependence of intramolecular and intermolecular vibrational modes revealed a solidification point at 6 kbar and a pressure-induced phase transition at 40 kbar. This solid-solid phase transition was identified as the III→IV phase transition by comparison with the intermolecular Raman spectra of the low-temperature solids at atmospheric pressure. The appearance of a dark-red modification of C4H4S, which is irreversibly formed at pressures above 80 kbar with laser irradiation, is discussed.

    High-pressure Raman study of dense methane: CH4 and CD4 (1995)

    Notizen: High-pressure Raman spectra of liquid and solid CH4 and CD4 were measured up to 18 and 13 GPa, respectively, at 300 K in a gasketed diamond-anvil cell. On the basis of visual observations under the polarizing microscope and changes in the Raman spectra, it was confirmed that there are only two solid phases (I and VII) for CH4 and CD4 at 300 K up to 18 GPa; no solid-solid phase transition was found around 12 GPa, in contrast to earlier claims. In phase VII, some molecules are orientationally ordered, whereas others are orientationally disordered, just like the low-temperature solid phases II, III, IV and V.

    High-pressure Raman study of liquid and crystalline CHF2Cl and CHF3 (1993)

    Notizen: High-pressure Raman spectra of liquid and crystalline CHF2Cl and CHF3 were measured up to pressures of 15 and 10 GPa, respectively, at 300 K in a gasketed diamond-anvil cell. The liquid-solid phase transition pressures were determined to be 3.49 GPa for CHF2Cl and 2.46 GPa for CHF3. For both CHF2Cl and CHF3, the wavenumbers of the C—H stretching mode ν1 increased rapidly with increasing pressure, and this behaviour was investigated by the theory of reasonance hybrid of the covalent-bonded and ionic-bonded structures.
