Available in PDF, EPUB and Kindle. Book excerpt: Spectrometric Techniques, Volume II provides information pertinent to vacuum ultraviolet techniques to complete the demonstration of the diversity of methods available to the spectroscopist interested in the ultraviolet visible and infrared spectral regions. This book discusses the specific aspects of the technique of Fourier transform spectroscopy. Organized into five chapters, this volume begins with an overview of the large number of systematic effects in the recording of an interferogram. This text then examines the design approach for a Fourier transform spectrometer with focus on optics. Other chapters provide a brief background to outline the scientific usefulness of Fourier spectrometers and present a calculation giving the optical path difference required to solve a Doppler-broadened spectral feature. This book discusses as well the importance of good mechanical design to minimize sampling error contributions by mechanical mechanisms and resonances. The final chapter deals with photon counting techniques to measure dispersed radiation. This book is a valuable resource for spectroscopists.

Available in PDF, EPUB and Kindle. Book excerpt: Many applications today require the Fourier-transform (FT) spectrometer to perform close to its limitations, such as taking many quantitative measurements in the visible and in the near infrared wavelength regions. In such cases, the instrument should not be considered as a perfect "black box." Knowing where the limitations of performance arise and which components must be improved are crucial to obtaining repeatable and accurate results. One of the objectives of this book is to help the user identify the instrument's bottleneck.

This book was released on 1983 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increasing prominence of the inductively coupled plasma (ICP), large amounts of spectrochemical information can be simultaneously obtained. Conventional measurement systems, including the direct reader and the scanning monochromator, are capable of measuring only a small portion of this information. The Fourier transform spectrometer (FTS) with its excellent simultaneous multielement measurement capabilities, should allow more complete utilization of the spectrochemical information generated by the ICP. In this laboratory, a Michelson interferometer has been developed, over the past fifteen years, specifically for measurements in the ultraviolet and visible regions of the spectrum. As a tool for the measurement of emission from the ICP, both the qualitative and quantitative capabilities of the FTS system have been examined in this thesis. The spectral characteristics of the ICP in the nearIR spectral region (0.7 to 3.0 pm) have been examined with the FTS as the measurement system. This region has previously been unexplored with the ICP and was found to have some usefulness for the analysis of nonmetals such as sulphur, carbon, oxygen and the halogens. In the ultraviolet and visible spectral regions, containing most prominent emission lines for metals, the FTS measurement system was found to have excellent spectral response, ranging from the far ultraviolet, 180 nm, to the near-IR spectral region. However, quantitatively the FTS system is limited by dynamic range limitations and increased background noise due to other emission lines in the spectrum. To improve the quantitative abilities of FTS, a new instrument, a windowed slew-scan Fourier transform spectrometer (WSSFTS), has been developed. This instrument consists of a slew-scanning monochromator with wide entrance and exit slits coupled to the Michelson interferometer. Accurate wavelength identification, resolution and simultaneous multielement measurement within a particular spectral window is provided by the interferometer while the monochromator provides a flexible method of selecting different spectral windows. Use of WSS-FTS reduces the dynamic range limitations imposed by strong emission lines and also reduces the signal-to-noise limitations. With WSS-FTS as the measurement system, detection limits measured were found to be comparable to those measured with a commercial ICP instrument, available in this laboratory. Windowed slew-scan Fourier transform should prove to be a viable alternative to measurement systems for emission from the future.

Available in PDF, EPUB and Kindle. Book excerpt: Introductory Fourier Transform Spectroscopy discusses the subject of Fourier transform spectroscopy from a level that requires knowledge of only introductory optics and mathematics. The subject is approached through optical principles, not through abstract mathematics. The book approaches the subject matter in two ways. The first is through simple optics and physical intuition, and the second is through Fourier analysis and the concepts of convolution and autocorrelation. This dual treatment bridges the gap between the introductory material in the book and the advanced material in the journals. The book also discusses information theory, Fourier analysis, and mathematical theorems to complete derivations or to give alternate views of an individual subject. The text presents the development of optical theory and equations to the extent required by the advanced student or researcher. The book is intended as a guide for students taking advanced research programs in spectroscopy. Material is included for the physicists, chemists, astronomers, and others who are interested in spectroscopy.

Available in PDF, EPUB and Kindle. Book excerpt: The final and largest volume to complete this four-volume treatise is published in response to the intense commercial and research interest in Fourier Transform Interferometry.Presenting current information from leading experts in the field, Volume 4 introduces new information on, for example, applications of Diffuse Reflectance Spectroscopy in the Far-Infrared Region. The editors place emphasis on surface studies and address advances in Capillary Gas Chromatography - Fourier Transform Interferometry.Volume 4 especially benefits spectroscopists and physicists, as well as researchers in physical, analytical, and surface chemistry.FROM THE PREFACE: Several reasons can be cited for the need to publish Volume 4 in this treatise.First, interest in Fourier transform interferometry (FT-IR) has continued. The number of commercial manufacturers of FT-IR instrumentation has increased, reflecting the increase in demand for such instrumentation. The main thrust in FT-IR instrumentation has focused on applications, and many techniques using FT-IR instrumentation have been generated in order to solve problems heretofore unsolvable. The interest in surfaces relative to catalysts, polymers, and electrical conductors has escalated. Three chapters in Volume 4 are devoted to surfaces. Second, the great acceptance of Volumes 1 through 3 and the demand to continue the treatise have induced us to publish Volume 4.The present volume contains nine chapters, making it the largest of the four volumes. Chapter 1 deals with infrared data processing techniques. Chapter 2 concerns itself with circular dichroism*b1FT-IR. Chapter 3 presents an update on GC*b1FT-IR, a rapidly moving field. Chapter 4 deals with the combination of FT-IR and thermal analysis. Advances in coal analyses using FT-IR are presented in Chapter 5. Reflectance studies are highlighted in Chapters 6, 7, and 8. Chapter 6 deals with structural characterizations made with Langmuir*b1Blodgett monolayers. Also in Chapter 6, the extension of DRIFT into the far-infrared region is shown to be feasible and valuable. Reflection*b1absorption surface studies (FT-IRRAS) are discussed in Chapter 8. Chapter 9 updates us on photoacoustic spectroscopy*b1FT-IR.All of the contributions are made by working experts in these areas. It is the hope that Volume 4 continues in the spirit of the purpose of these volumes, namely, to keep the scientific communities abreast of new developments in FT-IR as applied to chemical systems.
Download or read book Fourier Transforms in NMR Optical and Mass Spectrometry written by A.G. Marshall and published by Elsevier. This book was released on 2016-02-25 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by spectroscopists for spectroscopists, here is a book which is not only a valuable handbook and reference work, but also an ideal teaching text for Fourier transform methods as they are applied in spectroscopy. It offers the first unified treatment of the three most popular types of FT/spectroscopy, with uniform notation and complete indexing of specialized terms. All mathematics is self-contained, and requires only a knowledge of simple calculus. The main emphasis is on pictures and physical analogs rather than detailed algebra. Instructive problems, presented at the end of each chapter, offer extensions of the basic treatment. Solutions are given or outlined for all problems.The book offers a wealth of practical information to spectroscopists. Non-ideal effects are treated in detail: noise (source- and detector-limited); non-linear response; limits to spectrometer performance based on finite detection period, finite data size, mis-phasing, etc. Common puzzles and paradoxes are explained: e.g. use of mathematically complex variables to represent physically real quantities; interpretation of negative frequency signals; on-resonance vs. off-resonance response; interpolation (when it helps and when it doesn't); ultimate accuracy of the data; differences between linearly- and circularly-polarized radiation; multiplex advantage or disadvantage, etc.Chapter 1 introduces the fundamental line shapes encountered in spectroscopy, from a simple classical mass-on-a-spring model. The Fourier transform relationship between the time-domain response to a sudden impulse and the steady-state frequency-domain response (absorption and dispersion spectra) to a continuous oscillation is established and illustrated. Chapters 2 and 3 summarize the basic mathematics (definitions, formulas, theorems, and examples) for continuous (analog) and discrete (digital) Fourier transforms, and their practical implications. Experimental aspects which are common to the signal (Chapter 4) and noise (Chapter 5) in all forms of Fourier transform spectrometry are followed by separate chapters for treatment of those features which are unique to FT/MS, FT/optical, FT/NMR, and other types of FT/spectroscopy.The list of references includes both historical and comprehensive reviews and monographs, along with articles describing several key developments. The appendices provide instant access to FT integrals and fast algorithms as well as a pictorial library of common Fourier transform function pairs. The comprehensive index is designed to enable the reader to locate particular key words, including those with more than one name.
