Available in PDF, EPUB and Kindle. Book excerpt: The theory and practice of far-infrared, two-beam interferometry is summarized. A description of the instrumentation and performance of a two-beam, double-beam, far-infrared lamellar-grating interferometer is given. Detailed experimental measurements and analyses of the pure rotational spectra of the atmospheric molecules nitric oxide (NO) and water (H2O) are presented. Also discussed in depth are measurements of the optical constants of some important far-infrared window materials and the fabrication and performance of narrow bandpass filters for the far-infrared. Included is a discussion of noise, experimental errors, and problems in the practice of two-beam interferometry. Finally, a summary is given of the computational programs necessary and convenient for reducing the raw interferometric data to their more readily used spectral form.

Download or read book A High Resolution Far Infrared Double beam Lamellar Grating Interferometer written by Richard T. Hall and published by . This book was released on 1966 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high resolution far infrared lamellar grating interferometer which operates in either a single-beam or a double-beam differencing mode of operation is described. The instrument covers a frequency range of 10 to 125/cm (1000 to 80micron). To illustrate the general performance of the instrument, the pure rotational spectrum of water vapor between 15 and 115/cm is presented. It is estimated that the absorption line centers of strong isolated lines are measured to within + or - 0.008/cm. To illustrate the resolution of the instrument, low wavenumber portions of the pure rotational spectrum of DC1 are shown. The Cl35 -Cl37 isotope splitting of the J = 2 to 3 transition (32.3/cm) is clearly resolved. The calculated separation of these two lines is 0.904/cm. (Author).

Book excerpt: Research concerning the first practical application of Fourier transformation used to obtain high resolution spectroscopic information from two-beam interferometric observations is summarized. This procedure is applied in the far infrared by a lamellar grating interferometer. The procedures have been used to determine the spectra of gases and solids. A quantitative explanation of interference effects that produce the iridescence of crystals of KClO3 was developed. (Author).

Download or read book Introductory Fourier Transform Spectroscopy written by Robert Bell and published by Elsevier. This book was released on 2012-12-02 with total page 401 pages. 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.

Download or read book Infrared and Millimeter Waves V13 written by Kenneth J. Button and published by Elsevier. This book was released on 1985-11-28 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infrared and Millimeter Waves, Volume 13: Millimeter Components and Techniques, Part IV compiles the work of several authors while focusing on certain aspects of infrared and millimeter waves, such as sources of radiation, instrumentation, and millimeter systems. This volume covers millimeter components and techniques. This text first covers the use of powerful gyrotrons for thermonuclear research, and then discusses high-power coherent radiation sources. Kinetic theory of harmonic gyrotron oscillator with slotted resonant structure is the focus of Chapter 3, while integrated fin-line components for communication, radar, and radiometer applications is the subject of Chapter 4. The fifth chapter discusses propagation and mode coupling in corrugated and smooth-wall circular waveguides. Chapter 6 discusses far-infrared properties of inhomogeneous materials, and the last chapter covers solid-state spectroscopy with far-infrared continuous-wave lasers. This book will be of great use to researchers or professionals whose work involves infrared and millimeter waves.

Available in PDF, EPUB and Kindle. Book excerpt: Astronomy and Astrophysics Abstracts, which appears in semi-annual volumes, is devoted to the re cording, summarizing and indexing of astronomical publications throughout the world. It aims to pre sent a comprehensive documentation of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly issued abstracting journals, compared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user. Volume 2 contains literature published in 1969 and received before March 15, 1970; some older lite rature which was received late and which is not recorded in Volume 1 is also included. The authors of papers who have sent us abstracts on request have effectively contributed to the suc cess of our service. We should like to express our gratitude to them. We acknowledge with thanks con tributions to this volume by Dr. J. Bou~a, who surveyed journals and publications in Czech language and supplied us with abstracts in English, by Dr. B. Onderlicka, Brno, for providing English ab stracts of Russian papers, and by the Commonwealth Scientific and Industrial Research Organization (C.S.I.R.O.), Sydney, for providing titles and abstracts of papers on radio astronomy.
