Far Infrared Spectra

Raman spectra have been recorded of s-trinitrobenzene and s-trinitrobenzene-d3 both in solution and in the solid phase. Eighteen of the 22 Raman active fundamentals in D3h have been observed for both molecules.Two fundamentals have been observed in the far infrared spectrum of each molecule.

Three Phases

The far infrared spectra of four isotopic modifications of the partially orientationally ordered clathrate hydrate hexamethylenetetramine hexahydrate at 95 K are reported. The spectra are assigned to absorption allowed under the diffraction factor group, and to disorder-allowed absorption, following the theory for absorption by translational vibrations in orientationally disordered solids. Three phases formed primarily by hydrogen-bonded water molecules are known to be significantly, but only partially, orientationally ordered, hexamethylenetetramine hexahydrate, ice V, and ice VI. Of these phases, only ice VI fails to show sharp absorption in its far infrared spectrum in addition to the broad, disorder-allowed absorption.

Far Infrared Spectra

A number of different methods for preparing anionic Group 1B metal thiolate complexes have been investigated. The compounds [Me4N] [CU2(SMe)3] and [Et4N] [Ag5(SBut)6] are reported for the first time, and new methods for preparing the previously known compounds [Et4N] [Cu5(SBut)6], [Me4N]2 [CU5(SPh)7] and [Et4N]2 [Cu5(SPh)7] are described. The far-infrared spectra of the above compounds, and of CuSMe, CuSBut, AgSBut, [Me4N]2 [CU4(SPh)6] and [Me4N]2 [Ag5(SPh)7] have been obtained, and metal-sulfur stretching bands are assigned in the 150-350 cm-1 region. The low-frequency Raman spectra have also been obtained for some of these compounds. Possible structures for the new compounds are considered in the light of the low-frequency vibrational spectra.

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.
