These peaks are tentatively assigned to specific amino acid sidechains as indicated in Table 1. Table 1 Tentative assignment of Raman peaks in BSA-TR and Glycine-TR SER spectra resulting from protein (BSA) and linker (TR) parts. Full size table Tyrosine Raman peaks SERS has been previously ...
This could be a further confirmation of the assignment of the D1 peak to Frenkel defects, which are generally rather stable with the temperature50. A similar reversible behavior was observed for the two Mn-doped catalysts. On the other side, for the Ce95Cu5 sample the two spectra recorded ...
Full size table The Raman spectra of the horn fly feces exhibited higher similarity to the spectra of feces of Dermacentor and Ixodes, which were characterized by high levels of blood components (Table 1). The broad peak at around 1350–1400 cm−1 includes the vibrational frequencies at 1348...
For example, if the shifts of the most intense Raman peak of quartz at ca. 464 cm−1 are plotted against the unit-cell volume, then both the high-pressure and the low- and high-temperature data fall on a single trend [2]. This clearly demonstrates that the wavenumber of this ...
Peak assignment In the dry form, the peaks in the Raman spectra represent the vibrational modes of the protein via internal and surface phonons since there are no routes to a solvent. In the solvated aqueous form, there are both internal/surface vibrations of the protein solutes as well as ...

In either case, the user can edit the peak table through the "Peaks…" command. Profile shapes, locations, heights, FWHHs, and other parameters (i.e., percent Lorentzian) can be manually altered. Peaks can also be added or deleted either before or after iterations of the fitting routine....
