Indeed, Raman spectra of serum collected from ACS and control patients showed decrease of Raman peak around 1520 cm1 and increase of peak around 3050 cm1 in people with ACS. Moreover in people with ACS shift of peaks originating from amides II, I and lipids vibrations were noticed in ...

a consensus regarding the Raman spectra themselves; in particular, the Raman spectra of B1-ZrN are characterized by a low frequency doublet (150–275 cm−1), a broad envelope from 350 to 600 cm−1, and in some cases a very broad and weak peak at or just above 700 cm−1...
An example Raman spectra is that of Carbon Tetrachloride (CCl4) and is shown in Figure 3. CCl4 is a tetrahedral molecule with three pronounced Raman active vibrational modes in the 100 cm-1 to 500 cm-1 wavenumber region (there is an additional peak at ~780 cm-1 which is not shown). ...
Finally, a liquid nitrogen-cooled CCD detector was employed to acquire the Raman spectra of optically trapped cells.68 Progress in Raman spectroscopy technologies certainly has yielded large spectroscopic datasets that require advanced data analysis approaches rapidly.69,70 The identification of ...
This invention is a method to enhance by orders of magnitude accurate, real-time, stand-off detection by a sensor using Raman spectra of one or more trace compounds of interest (particularly explosives, bioterror organisms, or Volatile Organic Compounds). A colloid, whose medium of suspension is...
In the feature analysis, we decided on four important feature components from the Raman spectra that have the potential to give an accurate assessment of the oil palm fruit ripeness. The features are the position of the peaks, the peak intensity of sub bands, the peak height ratios, and the...
are often carried out in a single batch reactor. Figure2Ashows the Raman spectra for the initial reactants and the final crystalline product (proprietary). In this case, the product has a unique Raman peak at 1150 cm-1, suitable for monitoring formation, while the shift in the ...
With our analysis of the phonon modes in mind, we investigate the real-space distribution of the orbiton-related Raman peak intensities, which are involved in a local OO in our system. Figure 5a shows the zoomed-in Raman spectra for the high energy regime, normalized by the intensity of th...
In this verification routine a Raman spectra from the previously unused SERS surface is used to identify the surface to the spectrometer as one which is suitable for detecting heroin, or matches a surface that is authorized to be used with the spectrometer for a test selected on the ...
