Raman Spectrum of Fluorobenzene
The Journal of Chemical Physics, 1934The Raman spectrum of fluorobenzene has been investigated with a Hilger E1 quartz spectrograph, the following frequency shifts being obtained: 241, 517, 613, 804, 829, 997, 1009, 1157, 1220, (1265), (1414), 1496, (1561), 1599, 3076 and 3677 cm—1. Relative intensities were measured with a Zeiss three-prism glass spectrograph and a Moll microphotometer.

We report the first Raman scattering measurement of the rutile structure compound IrO2. The four allowed first-order Raman active phonon modes have been observed and classified. The spectrum exhibits strong lines of A1g and Eg symmetries, a slightly broadened line of B2g symmetry, and a very weak sharp low-frequency B1g mode.

Abstract It has been previously reported that the Raman effect is exhibited by rubber as a continuous scattering together with the presence of broad bands (Franklin and Laird, Phys. Rev., 36, 147 (1930); Busse, J. Phys. Chem., 36, 2862 (1932)). Busse attributed this result to the viscosity of the solutions or to the possibility that the rubber ...

The Raman spectrum of an oriented single crystal of CaSO4∙2H2O has been recorded from 20 to 3600 cm−1 at 300 °K and 77 °K using polarized laser excitation. The symmetries of the observed Raman lines have been determined and the spectrum has been analyzed in terms of external lattice vibrations, internal vibrations of the SO4 and H2O groups, hydrogen ...

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
