Surface-enhanced Raman Scattering (SERS) was first observed and later explained, in spectroelectrochemical experiments. The initial reports were all carried out on silver electrodes with modified roughened surfaces. This new phenomenon was clearly seen as a window of opportunity for surface Raman studies, and it by: The surface-enhanced Raman scattering (SERS) spectra were measured in two excitation wavelength ranges: (1) nm, and (2) nm, as well as with the nm line from a solid-state diode. The pH-dependent surface-enhanced Raman scattering (SERS) of 1,2,4-triazole adsorbed on silver electrode and normal Raman (NR) spectra of this compound in . A Surface-Enhanced Raman Scattering (SERS) spectrum of 4-cyanopyridine (4CNPy) was recorded on silver plasmonic nanoparticles and analyzed by using Density Functional Theory (DFT) calculations. Two simple molecular models of the metal–4CNPy surface complex with a single silver cation or with a neutral dimer (Ag+–4CNPy, Ag2–4CNPy), linked through the two Cited by: 4.

Gold and silver nanoparticles (NPs) were prepared in water, acetonitrile and isopropanol by laser ablation methodologies. The average characteristic (longer) size of the NPs obtained ranged from 3 to 70 nm. 4-Aminobenzebethiol (4-ABT) was chosen as the surface enhanced Raman scattering (SERS) probe molecule to determine the optimum irradiation time and the pH of aqueous Cited by: / Surface enhanced Raman scattering by isomeric monobromopyridines adsorbed on gold and silver sol particles, T. Takenaka, K. Eda, M. Mabuchi, Y. Fujiyoshi, N. Uyeda (Bulletin of the Institute for Chemical Research, Kyoto University ). The adsorption of l-cysteine (l-Cys) onto a polycrystalline silver electrode surface was investigated by in situ spectroelectrochemical methods. Surface-enhanced Raman spectroscopy (SERS) and surface-enhanced second-harmonic generation (SESHG) measurements were performed in a M KCl solution in the presence and absence of l-Cys. The experimental results indicated that l Cited by: Colloidal Ag suspensions including adsorbed pefloxacin, an antibacterial agent, were studied by photon correlation spectroscopy (PCS), ζ potential measurements, UV−vis absorption, and surface enhanced Raman scattering (SERS). These techniques provide complementary information about the particle size and state of aggregation as well as charge (re)distributions Cited by:

Abstract. This paper describes the use of Raman Scattering (RS) and, in particular, surface enhanced Raman Scattering (SERS) for the identification of atomic and molecular species absorbed on the surfaces of metals immersed in aqueous : T. M. Devine.   Abstract. Surface-enhanced Raman spectroscopy (SERS) is a spectroscopic technique that simultaneously combines fingerprint recognition capabilities, typical of vibrational spectroscopies, and very high sensitivity (down to single molecule), owing to the enhancement provided by plasmonic by: 4. Using picosecond excitation at nm, surface-enhanced hyper-Raman scattering (SEHRS) spectra of the nucleobases adenine, guanine, cytosine, thymine, and uracil with two different types of silver nanoparticles were obtained. Comparing the SEHRS spectra with SERS data from the identical samples excited at nm and with known infrared spectra, the major bands in Cited by: @article{osti_, title = {Surface-enhanced Raman spectra of 5,10,15,tetrakis(4-carboxyphenyl)porphyrin/silver colloid system: What information about the porphyrin do we obtain}, author = {Vlckova, B and Matejka, P and Pancoska, P and Baumruk, V and Kral, V}, abstractNote = {Porphyrins, both as free bases and as metal complexes, are involved in many .
