A. Tadayyoni and published by . This book was released on 1983 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent observation of surface-enhanced Raman scattering (SERS) for a variety of adsorbates at silver in electrochemical and gas-phase environments has generated a plethora of theoretical models to account for the remarkable (ca. 1,000,000 fold) observed enhancement of the Raman scattering intensities. These models can be divided into those demanding only the presence of the Raman scatterer at or close to the metal surface ('physical models'), and those requiring specific adsorbate-surface interactions ('chemical models'). Prompted in part by the especially intense SERS seen for specifically adsorbed species at silver electrodes, a widely held viewpoint is that the enhancement is due in part to chemical interactions between the Raman scatterer and the metal surface, possibly involving as adsorbate-adatom 'complex'. The report examines SERS of inorganic adsorbates at silver-aqueous interfaces. One objective is to examine systematically how the SER spectra are influenced by the nature of the adsorbate-surface interactions. A valuable class of adsorbates for this purpose is provided by substitutionally-inert Cr(III), Co(III), Ru(III) and Os(III) ammine complexes containing ligands such as thiocyanate, bromide, or pyrazine that bind strongly to silver electrodes.

Download or read book An Investigation of Inorganic Compound Scattering written by Karl Jay Bernstein and published by . This book was released on 2015 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Raman and its associated forms of spectroscopy are powerful tools that have been underutilized. Presented within are three studies of inorganic compounds performed with some form of Raman spectroscopy: normal Raman, hyper-Raman (HR), surface-enhanced Raman spectroscopy (SERS), surface-enhanced hyper-Raman spectroscopy (SEHRS), or resonance Raman spectroscopy (RR). The first study involves the investigation of phosphine binding with silver metal. Phosphines find wide use in synthetic circles yet have had little study into their method of binding, unlike similar compounds comprised of sulfur. In order to understand the binding of phosphines, several tertiary phosphines, secondary phosphines and secondary phosphine oxides are examined with SERS. SERS is a surface technique, providing a probe into the surface interaction of the phosphines and silver. By analyzing the results of SERS experiments and using the process of elimination, the secrets of phosphine binding begins to unravel. The second study involves the use of Raman spectroscopy, along with several other chemistry techniques to characterize a new uranium complex. This particular uranium complex is of interest due to applications to uranium capture and uranium sensing; however, this work did not progress to these points. Detailed in the study are the various facets concerning the complex, using many techniques for characterization. The third study centers around the investigation of uranium compounds with HR, RR and SEHRS. There are no published works on this subject to the author's knowledge. Non-linear spectroscopies such as HR offer the benefit of accessing modes forbidden to one-photon spectroscopies, such as traditional linear spectroscopies like Raman and IR. This can lead to new possibilities for identification and sensing not previously accessible.
Download or read book Surface Enhanced Raman Spectroscopy of Pentaammineosmium III II and Pentaammineruthernium II Containing Pyridine Pyrazine Or 4 4 Bipyridine Ligands at Silver Electrodes Vibrational Assignments written by S. Farquharson and published by . This book was released on 1984 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed vibrational assignments are described for Surface Enhanced Raman (SER) spectra of pentaamminoeosmium(III), (II) and pentaammineruthenium(II) containing pyridine (py), pyrazine (pz), and 4,4'-bipyridine (bpy) ligands adsorbed at the silver-aqueous interface. The assignments are based on group symmetry analysis, deuteration effects, and by comparison with corresponding normal Raman and infrared spectra for the solid-phase complexes and surface and bulk Raman spectra for the corresponding free ligands. Most bands present in the normal Raman and/or infrared spectra also appear in the SER spectra. This results from the high intensity of the SER spectra along with the relaxation of vibrational selection rules for adsorbed molecules. The appearance of intense SER spectra for Os(NH3)5py(III)/(II) and RuII(NH3)5py is noteworthy since unlike free pyridine, these lack an available nitrogen for surface coordination. The results illustrate the virtues of electrochemical SER spectroscopy for examining the detailed vibrational properties of coordination compounds, including those in oxidation states (such as Os(II) here) that are difficult to obtain pure in bulk media.

Available in PDF, EPUB and Kindle. Book excerpt: In the course of the development of surface science, advances have been identified with the introduction of new diagnostic probes for analytical characterization of the adsorbates and microscopic structure of surfaces and interfaces. Among the most recently de veloped techniques, and one around which a storm of controversy has developed, is what has now been earmarked as surface enhanced Raman scattering (SERS). Within this phenomenon, molecules adsorbed onto metal surfaces under certain conditions exhibit an anomalously large interaction cross section for the Raman effect. This makes it possible to observe the detailed vibrational signature of the adsorbate in the ambient phase with an energy resolution much higher than that which is presently available in electron energy loss spectroscopy and when the surface is in contact with a much larger amount of material than that which can be tolerated in infrared absorption experiments. The ability to perform vibrational spectroscopy under these conditions would lead to a new understanding about the chemical identity, geome try, and bonding of adsorbed material at a level previously unacces sible. It is for these reasons that the last few years have brought an explosion of activity surrounding the exploitation of SERS. The search for the origines) of the anomalous enhancement has given rise to a research sub-activity of its own. Efforts to explain the en hancement have led to an increased understanding of the whole range of phenomena associated with the interaction of photons with adsor bates and metal surfaces.

This book was released on 1993 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface-enhanced Raman (SER) spectra are reported for thin films of C60 and (eta 5-C9H7)Ir(CO)(eta2-C60) on gold electrodes in acetonitrile. The latter spectra display the hallmarks of vibrational symmetry lowering for C60 arising from metal coordination, involving splitting of the normally degenerate H (sub g) modes and the appearance of vibrationally forbidden bands. Only a milder selection rule relaxation is observed for SERS of uncoordinated C60. Electroreduction of both C60 and the Ir-C60 complex yielded similar frequency downshifts in the Ag pentagonal pinch mode, indicating that electron addition to the latter is fullerene localized. These spectral shifts are sensitive to the nature of the countercation.
