Raman Scattering Spectra

ABSTRACTNew experimental results obtained with various techniques on a less-studied glass-forming system are presented. At low frequency, a secondary βslow-process, decoupled from the viscous flow, is observed by 3 1P NMR. Raman scattering spectra and coherent neutron scattering spectra has been obtained in wide frequency and temperature ranges showing the same qualitative features for the Boson peak while the quasielastic contribution seems to differ markedly.

Dramatic Variation

Powder X-ray diffraction, Raman scattering and infrared spectra at different doping (x = 0 ~ 0.5) on polycrystalline Pr 1-x Sr 1+x CoO 4 were performed. With increasing x, the shift of Raman scattering spectra is due to the enhancement of electron–phonon interaction along the c-axis. The contrary variation of infrared in wavenumber comes from the weakening electron–phonon interactions in the ab plane. There is a dramatic variation in resistivity as x increases, which is also caused by increasing carrier concentration and is related to the band shift. For Pr 1-x Sr 1+x CoO 4, both A1g bands shift to low frequency and reach a minimum when x = 0.3 and the resistivity of Pr 0.7 Sr 1.3 CoO 4 is the smallest at room temperature.

Lattice Modes

Low frequency lattice modes of p-C6H4X2 (X = Cl, Br, I), m-C6H4I2, and o-C6H4I2 were observed by infrared absorption. Raman scattering spectra were recorded in the case of m-C6H4I2.When atomic positions were known in the unit cell (p-C6H4X2), the lattice mode frequencies were computed by the GF matrix method.The agreement between calculated and experimental values is reasonable although we did not consider the multipole–multipole long range interactions.
