The Raman spectrum of both gas and liquid PF5 has been obtained. The long-missing fundamental V7, has been identified with certainty at 174 cm−1 in the gas, and 177 cm−1 in the liquid. It is the second strongest band in the spectrum. This new value makes the previously-published ...
In this paper, the Raman scattering spectra of cold atomic gas in different environments are closely calculated. Comparing the spectra from the atoms in free and trapped environments, the calculation result gives a right spectrum structure for the free atoms and reveals a distinct high-gain spectrum...
in the Raman spectrum for these relatively low strain values that can be attributed to slippage, as was observed by Kumar and Cronin for nanotube bundles.19 Beyond this nominal strain value, we observed irreversible changes in the Raman spectra due to damage of the nanotubes. It is probable th...
In addition, it is known that the heterogeneity of tumour tissues and possible carcinoma infiltration increase the variability of spectral data collected from tissues. Therefore, it is necessary to collect a large number of spectra from each tissue sample to better represent the data, but this may...
After these steps are competed, resulting spectra will represent qualitative and quantitative data on species present in the sample. Here, we'll examine the Raman spectrum of carbon nanotubes, which are very small, hollow single or multi-layered rolls of graphene sheets. The Raman spectrum taken ...
However, it has only acted as a supplement to tech- niques using the infrared spectrum because of its low efficiency, as only one of every 108 incident photons is scat- tered to produce a Raman signal. Early work in the 1970s on Raman scattering using pyridine molecules on the rough ...

A colloid, whose medium of suspension is a liquid solvent with a weak Raman spectrum and in which are suspended particles of a noble metal that are preferentially nano-sized to maximize the surface-to-mass ratio for each particle, forms an impingement base. A sample of this colloid is air-...
Instead, at the end of the test, when the shielding effect of soot is not present anymore, the defects band in the spectrum of the tablet is clearly more intense than that of the spectrum recorded on the pure catalyst. The huge increase of the D1 and especially the D2 band of Ce95...
The spectra in selected regions at different annealing temperatures are shown in Figures S1 and S2 of the Supporting Information (SI). To characterize the concentration effect, we collected the isotropic and anisotropic spectrum in series at a variety of volume fractions of acetone. The Raman ...
