The Raman peak table obtained by the DFT calculations was useful for assigning the Raman peaks measured by the experiments. The assignment of the Raman peaks of the C-H stretching mode of each fluoromethane hydrate coincided well with those estimated both experimentally and theoretically ill ...
Abstract: Raman spectra of aluminosilicate minerals of kyanite, andalusite, and sillimanite were determined. The Raman vibration frequencies of the three minerals were calculated by Materials Studio 3.0 software. The normal mode of vibration was analyzed, and description of the characteristic peak of ...

For Raman imaging of virus-infected cells and measurements, the central wavelength of gating was set at 610 nm (which presents the common setting for Raman cell imaging), showing the “fingerprint region” from 400 to 1800 cm−1, the C-H peak at 2800–3100 cm−1. Each Raman ...
(Supplementary Table2). The fact that the match does not reach 100% can most likely be explained by instability of the Raman system (including laser and optical alignment) and signal fluctuation from the SERS NPs. For example, instability of the laser power, variation of the photon detection ...
that in the cancer tissue group (Student’st-test,P < 0.05). Hierarchically clustered heatmaps of characteristic Raman peaks were plotted to pre-discriminate the closely related Raman peaks (Supplementary Fig.3). Supplementary Table2gives the peak position and corresponding representative ...
(Table2). They found that their Raman images had similar characteristic peaks with the known spectra measured from pure chemicals. For example, the spectra of cytoplasm and synthetic actin are highly similar, while major differences can be seen at 1003cm−1−1phenylalanine peak, 1081 and ...
Using the correlation function of the disorder of a Gaussian form, one arrives at the Boson peak of an asymmetric quasi-Gaussian profile. However, it is S.A. Kirillov, O.F. Nielsen / Journal of Molecular Structure 526 (2000) 317–321 319 Table 1 Parameters of data fits Parameter and ...
5a). Under the substitution of 13C-AA, the Raman peak at 1574 cm−1 and 1659 cm−1, ascribed to cellular amide II and amide I, will shift to lower wavenumber by about 40 cm−1, as a result of the 13C containing amide bonds in the newly synthesized protein51. The ...
The peak at 1470 cm−1 is tentatively assigned to C-H32. This peak is detected in the low loadings spectra g and h in BSA-TR, and in the low loading spectra of b in Glycine-TR. The low loading Glycine-TR sample was primarily used as a control to get its SER spectroscopic ...
