This book was released on 2012-12-06 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains all of the papers presented at the American Chemical Society Symposium on Reflectance Spectroscopy. The Symposium was presented under the sponsorship of the Division of Analytical Chemistry, and was held on September 11 and 12,1967, at the 154th National Meeting of the American Chemical Society, Chicago, Illinois. The papers presented herein represent a renaissance of interest in reflectance spectroscopy. The techni~ue of reflec tance spectroscopy is not, of course, a new techni~ue, however, it has only been applied to problems of a chemical interest in the last decade or so. The instrumentation for this techni~ue in the ultraviolet, visible, and near infrared regions of the spectrum has been available for many years. New and exciting research is being carried out at the present time to extend these techni~ues to the infrared and far infrared regions as well. It is a pleasure for the Editor to express his gratitude to Drs. John K. Taylor and E. C. Dunlop of the Division of Analytical Chemistry, ACS, for their cooperation in making the Symposium a reality. The assistance of Miss Julie Norris of the University of Houston for her typing and manuscript organi zation skill is greatly appreciated. And lastly, but certainly not the least, the Editor would like to acknowledge the coopera tion of all of the contributors to this volume. Certainly without their cooperation, this Symposium would not have been a success.

Available in PDF, EPUB and Kindle. Book excerpt: The main subject division of this book include the theory of Diffuse reflectance spectroscopy; measurement and standardization of diffuse reflectance; instrumentation; application to color measurement and physical, inorganic, and organic chemistry; and applications in chromatographic analysis.While the use of reflectance spectroscopy dates from the 1920s, it has only been in the last decade that its analytical potential has been developed. Interestingly, much of the early research involved industrial uses where measurement of color was required. The development and acceptance of thin-layer chromatography has opened up new areas of analysis for the application of this technique.It is not the purpose of this book to delve deeply into the theoretical aspects of reflectance spectroscopy, as this book has already been done in several previous books. Insofar as it is possible, this book is an up-to-date guide to instruments and techniques intended primarily for the chemical analyst, though it is hoped that it may contain information of interest to other scientists. The potential for the application of this technique is great and the authors feel confident that the coming decade will see many interesting developments in this type of spectroscopy study, particularly in the field of analysis.

Available in PDF, EPUB and Kindle. Book excerpt: Reflectance spectroscopy is the investigation of the spectral composi tion of surface-reflected radiation with respect to its angularly dependent intensity and the composition of the incident primary radiation. Two limiting cases are important: The first concerns regular (specular) reflection from a smooth surface, and the second diffuse reflection from an ideal matte surface. All possible variations are found in practice between these two extremes. For the two extreme cases, two fundamentally different methods of reflectance spectroscopy are employed: The first of these consists in evaluating the optical constants n (refractive index) and x (absorption index) from the measured regular reflection by means of the Fresnel equations as a function of the wave A. This rather old and very troublesome procedure, which is length incapable of very accurate results, has recently been modified by Fahren fort by replacing the air-sample phase boundary by the phase boundary between a dielectric of higher refractive index (n ) and the sample (n ). 1 2 If the sample absorbs no radiation and the angle of incidence exceeds a certain definite value, total reflection occurs. On close optical contact between the two phases, a small amount of energy is transferred into the less dense phase because of diffraction phenomena at the edges of the incident beam. The energy flux in the two directions through the phase boundary caused by this is equal, however, so that 'total reflection takes place.

Available in PDF, EPUB and Kindle. Book excerpt: to the Fundamental and Applied Catalysis Series Catalysis is important academically and industrially. It plays an essential role in the manufacture of a wide range of products, from gasoline and plastics to fertilizers and herbicides, which would otherwise be unobtainable or prohibitive ly expensive. There are few chemical-or oil-based material items in modern society that do not depend in some way on a catalytic stage in their manufacture. Apart from manufacturing processes, catalysis is finding other important and over-increasing uses; for example, successful applications of catalysis in the control ofpollution and its use in environmental control are certain to in crease in the future. The commercial import an ce of catalysis and the diverse intellectual challenges of catalytic phenomena have stimulated study by a broad spectrum of scientists including chemists, physicists, chemical engineers, and material scientists. Increasing research activity over the years has brought deeper levels of understanding, and these have been associated with a continually growing amount of published material. As recentlyas sixty years ago, Rideal and Taylor could still treat the subject comprehensively in a single volume, but by the 19 50s Emmett required six volumes, and no conventional multivolume text could now cover the whole of catalysis in any depth.

Available in PDF, EPUB and Kindle. Book excerpt: Until comparatively recently, trace analysis techniques were in general directed toward the determination of impurities in bulk materials. Methods were developed for very high relative sensitivity, and the values determined were average values. Sampling procedures were devised which eliminated the so-called sampling error. However, in the last decade or so, a number of developments have shown that, for many purposes, the distribution of defects within a material can confer important new properties on the material. Perhaps the most striking example of this is given by semiconductors; a whole new industry has emerged in barely twenty years based entirely on the controlled distribu tion of defects within what a few years before would have been regarded as a pure, homogeneous crystal. Other examples exist in biochemistry, metallurgy, polyiners and, of course, catalysis. In addition to this of the importance of distribution, there has also been a recognition growing awareness that physical defects are as important as chemical defects. (We are, of course, using the word defect to imply some dis continuity in the material, and not in any derogatory sense. ) This broadening of the field of interest led the Materials Advisory Board( I} to recommend a new definition for the discipline, "Materials Character ization," to encompass this wider concept of the determination of the structure and composition of materials. In characterizing a material, perhaps the most important special area of interest is the surface.

Available in PDF, EPUB and Kindle. Book excerpt: Spectroscopy in Heterogeneous Catalysis deals with the applications of spectroscopy in heterogeneous catalysis. The concepts and capabilities of a particular technique, experimental procedures, and examples of all proven or potentially important applications are discussed. The use of spectroscopic measurements in guiding empirical approaches to applied problems and to fundamental studies of the chemical identity of catalytic surfaces is also described. This book is comprised of eight chapters and begins with a discussion on the scope of spectroscopy in catalysis and applications of spectroscopy to zeolite catalysts. The following chapters focus on infrared spectroscopy, with emphasis on the theory and interpretation of infrared spectra; Raman spectroscopy and the theory of the Raman effect; diffuse reflectance and photoacoustic spectroscopies; and Mössbauer spectroscopy. Electron spin resonance spectroscopy and nuclear magnetic resonance spectroscopy are also considered. The final chapter is devoted to X-ray photoelectron spectroscopy (XPS) and its application to core electrons, along with the experimental equipment and procedures used. The applications of XPS to studies of surface behavior and catalyst composition and chemistry are outlined. This monograph will be a useful resource for physicists, researchers, and potential researchers in heterogeneous catalysis.
