V. Raman1 leads in the case of diamond to the result2,3 that the atomic vibration spectrum of this crystal should exhibit eight distinct monochromatic frequencies. Of these, the highest frequency (1,332 cm.-1 in spectroscopic units) corresponds to the triply degenerate vibration of the two ...
In the course of an examination of the infra-red and ultra-violet regions of the spectrum of a large number of diamonds, we have come across one which, unlike the others, is transparent both at about 8μ, and also in the ultra-violet so far out as λ2300. This diamond was ...

vibrational modes with the structure and symmetry of the molecules are discussed. Each diamondoid was found to produce a unique Raman spectrum, allowing for easy differentiation between molecules. Using the peak assignments derived from the calculations we find that the low ...

The sharp peak in the second-order Raman spectrum of diamond has been studied at temperatures between 4 and 300°K. We find its width to be 4.2 ± 1 cm-1 and its peak intensity, relative to the second-order feature at 2450 cm-1 to be 0.37 ± 0.01, both being temperature independent...
A further controversy unfolded over a long upheld dispute with the German physicistMax Bornover the vibration spectrum of diamond, an argument where posterity has found him in the wrong. Nonetheless, he made many significant contributions to physics, and the institutions he founded and helped establi...
The second one is observed at 28GPa, where the sample decomposes suddenly just after shear application. Examination of the black residue showed that it is composed of carbon, as indicated by the Raman spectrum.doi:10.1080/08957950903513796
Raman spectrum of diamond with natural linewidths of around 1.8 cm−1 was used for the determination of the spectral apparatus function73 (see Supplementary Figs. S7–S9). The result of spectral deblurring is shown in Figs. S10–S12 (see supplementary note S2). Figure 1m illus- trates ...
Raman active phonon and sp2/sp3 ratio in diamond/Si(100) films were investigated by Raman spectra in the difference scattering configurations. Furthermore, the Raman scattering spectrum of diamond/Si (100) hetero-junction was measured with different thickness to investigate the spin dynamics of ...
