Available in PDF, EPUB and Kindle. Book excerpt: Almost 30 years after the first reports on surface-enhanced Raman signals, the phenomenon of surface-enhanced Raman scattering (SERS) is now well established. SERS gained particular interest after single-molecule Raman spectroscopy had been demonstrated. This book summarizes and discusses present theoretical approaches that explain the phenomenon of SERS and reports on new and exciting experiments and applications of the fascinating spectroscopic effect.

Download or read book Application of Raman Spectroscopy Surface enhanced Raman Scattering SERS and Density Functional Theory for the Identification of Phenethylamine and Its Analogs written by Francis Taplin and published by . This book was released on 2011 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated normal Raman (NR) spectroscopy and the surface-enhanced Raman scattering (SERS) for the analysis of five sympathomimetic amines. Furthermore, quantum mechanical calculations -- geometry optimization and calculations of the harmonic vibrational frequencies -- were performed using the Density Functional Theory approach. Vibrational assignments were made by comparing the experimental and calculated spectra. Traditionally, drugs of abuse are analyzed by color test, GC-MS, and Infrared spectroscopy. However, there has been continuing and growing interest in applying Raman spectroscopy and surface-enhanced Raman scattering techniques for the identification of street drugs as they offer some clear advantages over previously used methods. Five commonly seized phenethylamines and their precursors were chosen. Normal Raman and SERS spectra were successfully obtained for each of the drug molecules. The normal Raman and SERS spectra were determined with 514nm, 633nm, and 1064 nm laser wavelenghts. SERS spectra were obtained with addition of a silver (Ag) colloid and 0.5M NaCl aggregating agent. The study found that both NR and SERS provided excellent spectra for the drugs tested. Certain conditions, such as response to various laser wavelengths and background fluorescence of the analyte could be easily managed using SERS techniques. The DFT calculated spectra could be correlated with the experimental spectra without the aid of a scaling factor.

Download or read book The Application of SERS Surface Enhanced Raman Scattering to Study Surface Oxidation Reactions of Phosphonates written by Paul B. Dorain and published by . This book was released on 1988 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface enhanced Raman scattering has developed into an important spectroscopic tool in the identification of adsorbates on silver, copper, or gold under in situ conditions. This paper describes the first use of this technique to study the kinetics of surface enhanced catalyzed chemical reactions. The reaction of NO2 gas with Ag powder is shown to proceed through the formation of AgNO2 which autocatalytically decomposes into AgNO3, NO, and free Ag which forms Ag microstructures. Recent experiments to elucidate the reactions of DMMP at these catalytically active sites show that H2PO4 and HPO4 are formed on the surface at room temperature. The use of dynamically produced active Ag sites as active filters for phosphonates is discussed. Keywords: Surface Enhanced Raman Scattering (SERS), Phosphonates, Kinetics, Catalysis.
