Raman spectrum of superconducting oxides
Physical Review B, 1992The anomalous electronic Raman scattering in the normal state of various cuprates extends smoothly to an energy of 1 eV. This behavior is shown to be in accord with the frequency-dependent damping caused by electron-electron scattering between nearly parallel (i.e., nested'') sections of the Fermi surface.

Raman Spectrum of Benzene Vapour
Nature, 1937The Raman spectra of benzene in the liquid and vapour states have been photographed alongside each other under identical conditions of slit width and illumination. While the 600 and 992 Raman lines show no shift, the line at 3061 shifts to 3069 as we pass from the liquid to the vapour. The Raman line at 3047 observed in the liquid has either completely

Raman Spectrum of Potassium Bromide
Nature, 1949POTASSIUM bromide has a crystal structure similar to that of rocksalt ; but as the ions in the former are heavier, the Raman frequency shifts are smaller and hence less easy to record in a satisfactory manner. The success of Menzies and Skinner1 in observing some detail in the Raman spectrum of the substance, however, encouraged us to undertake an ...

Raman spectra of the anthracene solution are recorded using a Raman source of high luminosity. Twelve new frequencies are found and an assignment is proposed using earlier measurements on a single crystal.

Science, 1933
THE Raman spectrum of 80 per cent heavy water obtained with a sample supplied by Prof. H. S. Taylor of Princeton, when compared with the spectrum of the 18 per cent material previously reported1, shows that the water molecule with two atoms of heavy hydrogen gives a Raman band with a frequency difference of 2517, while the molecule with one atom of ...

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.

Solid State Communications, 1989
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.

Rubber Chemistry and Technology, 1935
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 ...
