Laser-excited Raman spectra of polycrystalline samples of chlorine, bromine and iodine have been observed at low temperatures. Lattice and molecular modes in Cl 2 and Br 2 are assigned according to group theory, and isotope effects are distinguished. Strong crystal field perturbations are observed fo...
Surface-enhanced Raman scattering assessment of DNA from leaf tissues adsorbed on silver colloidal nanoparticles In this work, the surface-enhanced Raman scattering (SERS) spectra of seven genomic DNAs from leaves of chrysanthemum (Dendranthema grandiflora Ramat.), co... C.,M.,Muntean,... - 《...
A surface-enhanced Raman scattering (SERS) substrate containing silver particles was prepared by an acid-catalyzed sol−gel method. Silver nitrate was first doped into the sol−gel film followed by chemical reduction of the silver ions with sodium borohydride to produce silver particles. This sil...
Figure 5: TERS signal and SERS spectra of silver nanoaggregates before and after correction. (a) TERSrawspectra for a gold tip near a flat gold surface, the latter covered by 4-chlorophenyl isocyanide molecules (solid lines), and corresponding background Bg (dashed lines). The two sets of...
The standard (STD) SERS spectra of the CV-ethanol solution is provided after scaling for clarity. In the CV-specific window of 780 to 820 cm−1, a weak peak was observable at concentrations from 10−10 to 10−12 M, but no peak was evident at concentrations lower than 10−...
After the addition of all the silver nitrate solution, the resulting yellow/orange/grey solution must be stirred for approximately 15 min. The final solution has to be wrapped with foil to avoid light degradation of the colloidal mixture. To collect the SERS spectra, a hand-held Bravo Raman ...
Nevertheless, nitric acid and silver nitrate peaks were found in Raman spectra confirming the unstable and noxious environment inside de aluminum can and proving that Raman microscopy can be a valuable complementary in situ technique for cellulose nitrate degradation studies....
At first, Raman spectra of Strep@mPS-AuNPs or Strep@mPS-AgNPs were collected. The Strep@mPS-AuNPs composite with thorny morphology of Au particles proved to be the most effective substrate for the surface enhanced Raman spectroscopy experiments (Strep@mPS-tAuNPs) and it utilized for all the ...
tetranitrate (PETN), (c) 10−5 M cyclotrimethylenetrinitramine (RDX), (d) 10−9 M glucose. Raman spectra collected from pure reference powders/liquids. Each spectrum was collected with the same conditions, giving the increase in intensity for the PIERS spectra, and full collection ...
