Das Schwingungsspektrum von Magnesium-orthovanadat

The infrared and laser-Raman spectra of crystalline Mg₃(VO₄)₂ are reported and a factor group analysis for the full lattice is presented to support the discussion. The 1,000 to 600 cm^?1 region of the spectrum is essentially related to internal (stretching) modes of the greatly distorted VO₄ tetrahedra, whereas the bands in the low frequency region must be assigned to complex vibrations originating in the interaction of the bending vibrations of the tetrahedral groups with the external modes.

Das Schwingungsspektrum von Sr2V2O7 und die Schwingungseigenschaften des Divanadat-Ions

The infrared and laser-Raman spectra of Sr₂V₂O₇ are reported and discussed by means of a Site Symmetry analysis. The principal force constants as well as the mean amplitudes of vibration for the V₂O₇ ^4– ion have been calculated using a simplified molecular model. Some aspects of the vibrational behaviour of the V–O–V bridge in this ion are also discussed.

Das Schwingungsspektrum von Li5ReO6

The infrared and laser-Raman spectra of crystalline Li₅ReO₆ are reported and discussed and some comparisons with other lithium hexaoxometallates are made.     

Das Schwingungsspektrum von Ba2ZnTeO6

The Vibrational Spectrum of Ba₂ZnTeO₆ The vibration modes of Ba₂ZnTeO₆ are assigned to TeO₆ octahedra linked by apexes and sharing faces respectively. Both octahedra types show different force constants, bond order, and Te? O distances.     

Schwingungsspektrum und kraftkonstanten des cyclopentasilans

The Raman and infrared spectra of cyclopentasilane, Si₅H₁₀ (and Si₅D₁₀), the first cyclic silicon hydrogen compound, have been measured and assigned. Analogous to cyclopentane, cyclopentasilane is not planar and undergoes rapid pseudorotation. A complete normal coordinate analysis has been performed using isotopic data. The SiSi stretching force constant is calculated to be 1.68 N/cm.
