Book excerpt: Studies of the Raman and infrared spectra of several molecules adsorbed to metal surfaces indicate that special selection rules govern these spectra. In the case of infrared reflection adsorption spectroscopy (IRS) as in the related techniques of electron energy loss spectroscopy (ELS) and inelastic electron tunneling spectroscopy (IETS), only modes which develop dipole moment perpendicular to the metal surface can be excited. Both infrared and Raman spectra of oriented metal adsorbates can be used to probe molecular orientation. Depolarization ratios for specific orientations and scattering geometries have been derived and used to analyze the results of several experimental examples. The adsorbed molecule whose Raman spectrum has been most thoroughly studied is pyridine on silver. Using secondary ion mass spectroscopy, we have been able to show that the silver surfaces are atomically quite clean. The case of pyridine adsorbed on Ag is also of interest because of the relative intensity of some of its Raman lines. By comparison with the same lines in liquid pyridine, the intensity is apparently enhanced by a factor of 10000. Several theories of this enhancement are analyzed.

Available in PDF, EPUB and Kindle. Book excerpt: SERS was discovered in the 1970s and has since grown enormously in breadth, depth, and understanding. One of the major characteristics of SERS is its interdisciplinary nature: it lies at the boundary between physics, chemistry, colloid science, plasmonics, nanotechnology, and biology. By their very nature, it is impossible to find a textbook that will summarize the principles needed for SERS of these rather dissimilar and disconnected topics. Although a basic understanding of these topics is necessary for research projects in SERS with all its many aspects and applications, they are seldom touched upon as a coherent unit during most undergraduate studies in physics or chemistry. This book intends to fill this existing gap in the literature. It provides an overview of the underlying principles of SERS, from the fundamental understanding of the effect to its potential applications. It is aimed primarily at newcomers to the field, graduate students, researchers or scientists, attracted by the many applications of SERS and plasmonics or its basic science. The emphasis is on concepts and background material for SERS, such as Raman spectroscopy, the physics of plasmons, or colloid science, all of them introduced within the context of SERS, and from where the more specialized literature can be followed. Represents one of very few books fully dedicated to the topic of surface-enhanced Raman spectroscopy (SERS) Gives a comprehensive summary of the underlying physical concepts around SERS Provides a detailed analysis of plasmons and plasmonics
Download or read book Surface Enhanced Raman Scattering written by Richard Chang and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 424 pages. 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.

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.

Schatz and published by . This book was released on 1980 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: An image field theory of surface enhanced Raman spectroscopy is used to study the dependence of Raman intensities on light frequency, nature of adsorbate and metal, electrode potential, scattering angle and light polarization. Although the image field enhancement (IFE) theory is at best a crude approximation to the true enhancement mechanism, it does find quite reasonable agreement between the IFE predictions and most existing experimental results.
