Infrared And Raman Spectra

The infrared spectra (500-40 cm-1) of crystalline (Me4N)2HgCl4, Me4NHgCl3, and (Et4As)2HgI4, and the Raman spectra of the first two compounds, have been recorded. Assignments of the vibrational frequencies are made and discussed in relation to the structure of the anions.

Far Infrared Spectra

The Raman and far-infrared spectra of crystalline cyanogen iodide have been recorded. High-frequency shoulders alongside the Raman bands confirm the piezoelectric nature of this solid and allow an estimate to be made of the frequencies of the longitudinal modes associated to the fundamental vibrations. Dipole derivatives calculated from these frequencies agree qualitatively with those obtained from infrared band intensity measurements.

Far Infrared Spectra

The far-infrared spectra of thin films of NH4F and ND4F and the Raman spectra of polycrystalline samples of both compounds have been recorded at −170°C. Two low-frequency lattice vibrations were observed in each spectrum and these have been assigned as optical translations on the basis of their isotopic shift factors. Librational modes were not observed in any of the spectra.

Abstract The infrared and Raman spectra of silver thiophosphate Ag3PS4 have been recorded. The observed frequencies are assigned on the basis of tetrahedral units by considering a splitting of the F2 modes by the crystal field. The vibrational frequencies of copper thiophosphate Cu3PS4 are completed for the far infrared region. For both title compounds DTA-data have been determined and interpreted.

Pb2P2Se6 crystallizes in the monoclinic system, space group Pn (No. 13) with the lattice constantsa = 974.2 (4) pm. b = 766.2 (3) pm. c = 689.8 (3) pm, β=91.44(5)°.The title compound is isotypic to the homologous Pb2P2S6. In the structure there are discrete P2Se4-6 anions.Far infrared, infrared and Raman spectra of this compound have been recorded. The observed frequencies are assigned on the basis of P2Se4-6 units with C2h symmetry in the crystal. DTA-data have been determined and interpreted.

Far infrared, infrared and Raman spectra of tin hexathiohypodiphosphate Sn2P2S6 (mono­clinic modification II) have been recorded. The observed frequencies are assigned on the basis of P2S64-units with C2h symmetry in the crystal. The assignment is supported by the correlation D3d (dissolved P2S64- ion) → C2h. DTA-data have been determined and interpreted.
