Twist Mode

Infrared and Raman spectra have been measured for spiropentane-H8. Raman spectra for the liquid have enabled the b1 species ring twist to be assigned. Previous assignments of this mode were based on calorimetric data and on the assignment of a band in the infrared spectrum to a combination band involving the ring twist mode. Infrared spectra of low temperature crystalline films have provided sufficient information that, when taken with the Raman data and gas phase infrared spectra, we have assignments for all of the fundamental modes.

The Gas Phase Raman Spectrum and Molecular Structure of Dichlorodibromotellurium(IV) TeCl2Br2. Novel Penta- and Hexa-co-ordinate Mixed Halide Anions of Tellurium(IV). Synthesis and infrared and Raman Spectra of [Et4N]TeCl2Br3 and [Et4N]2TeCl2Br4

First Time

The Raman spectrum of gaseous TeCl2Br2 at 310 °C is reported for the first time. The gas phase data is consistent with the presence of a monomolecular species haying C1 symmetry. A synthetic route for the preparation of penta- and hexa-co-ordinate mixed halide anions of tellurium(IV), under anhydrous conditions, is described for the first time. The infrared and Raman spectra for solid [Et4N]TeCl2Br3 and [Et4N]2TeCl2Br4 are reported. A stereochemistry based on a square pyramid, is favored for [Et4N]-TeCl2Br3. In the case of [Et4N]2TeCl2Br4 the vibrational data strongly suggests the presence of a cis-octahedral anion, having C2v symmetry.

Successful Observation

The failure to observe a microwave spectrum of dichloroketene prepared in a low temperature flow system is contrasted with the successful observation of its Fourier Transform infrared spectrum under the same conditions. It is concluded that the lack of a microwave spectrum is a result of a near-zero dipole moment for dichloroketene.
