Abstract The Raman spectrum of tellurium was measured at room temperature and the temperature of liquid nitrogen. Five peaks were seen at both temperatures which can be associated with the normal modes of vibration of the D 3 point group for a three-atom molecule.

Raman Spectrum of Monodeuteroethylene
Nature, 1937MONODEUTEROETHYLENE has been prepared (J.C.J.) in two different ways. Starting from vinylbromide and deuterium bromide, obtained by the action of deuterium oxide on redistilled phosphorus penta-bromide, the monodeuteroethylenebromide was prepared. This compound was submitted to the action of zinc and yielded monodeuteroethylene.

Abstract The Raman spectrum of BaTiO3 is investigated in the tetragonal and the cubic phase, where it is found that two strong transitions are still present. The temperature dependence of the intensities for the lines perculiar to the tetragonal phase correlates well with the presence of a tetragonal distortion.

The Raman spectrum of magnesite (MgCO3) has been investigated and found to be analogous in its features to that of calcite, as is to be expected in view of the similarity of structure. The frequency shifts observed are: 212 (w), 332 (st), 735 (w), 1096 (st) and 1460 (?) cm.−1 All the frequencies and especially the two lowest are notably higher than for

Using λ2536.5 mercury resonance radiation as exciter, the Raman spectrum of a single crystal of anhydrite has been investigated for three different orientations. Besides the nine Raman lines due to the sulphate ion, the recorded spectrum exhibits eight of the nine lattice lines to be expected theoretically. Their frequency shifts are 62, 126, 135, 151,

Raman spectrum of difluorodiazirine
Spectrochimica Acta Part A: Molecular Spectroscopy, 1979Abstract The Raman spectrum of difluorodiazirine has been re-examined. Four well-defined bands have been found in the low frequency region, which lead to a definitive assignment for all nine vibrational fundamentals of this molecule. The fundamental frequences are (in cm −1 ): ( a 1 ) 1563, 1282, 805, 502; ( a 2 ) 451; ( b 1 ) 1248, 481; ( b 2 ...

Raman spectra are reported from single crystals of graphite and other graphite materials. Single crystals of graphite show one single line at 1575 cm−1. For the other materials like stress-annealed pyrolitic graphite, commercial graphites, activated charcoal, lampblack, and vitreous carbon another line is detected at 1355 cm−1.

Raman Spectrum of Triethylborane
The Journal of Chemical Physics, 1957Frequency shifts and polarization data are reported for the Raman spectrum of liquid triethylborane, B(C2H5)3. By comparison with the spectra of trimethylborane and ethane, tentative assignments are made for most of the observed bands.
