Download or read book A Theory of Spectral Line Shape for Atmospheric Absorption Part III written by and published by . This book was released on 1995 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: The non-Lorentzian nature of the far wings of spectral line shapes is an important phenomenon in the description and modelling of atmospheric transmission. Fano (1963) developed an approach to spectral line theory whose essential basis was the definition of a collision super operator which is a function of the frequency of the applied radiation field. This paper evaluates the frequency dependence of the complete Fano operator using previously developed collision time theory. The paper begins with a review of the nature of the terms in the Fano operator as discussed by that author, then summarizes the collision time theory results. The paper applies this theory to each of the terms of the Fano operator and examines the contributions to the near and far line wing. Experimental confirmation for the line wing behavior is also presented.

Download or read book Pressure Broadening of Spectral Lines written by Peter Joseph Rayer and published by Cambridge University Press. This book was released on 2020-08-06 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presenting the quantum mechanical theory of pressure broadening and its application in atmospheric science, this is a unique treatment of the topic and a useful resource for researchers and professionals alike. Rayer proceeds from molecular processes to broad scale atmospheric physics to bring together both sides of the problem of remote sensing. Explanations of the relationship between a series of increasingly general theoretical papers are provided and all key expressions are fully derived to provide a firm understanding of assumptions made as the subject evolved. This book will help the atmospheric physicist to cross into the quantum world and appreciate the more theoretical aspects of line shape and its importance to their own work.
Download or read book Spectral Line Formation written by John T. Jefferies and published by . This book was released on 1968 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to discuss certain aspects of the theory of the formation and analysis of the line spectrum of a hot gas. The underlying motivation for most of the studies discussed here lies in a desire to develop a physically sound procedure for interpreting the line spectrum of a stellar atmosphere ; correspondingly, the major emphasis is given to problems encountered in astrophysics.

Download or read book Spectral Line Shapes in Astrophysics and Related Topics written by Milan S. Dimitrijević and published by MDPI. This book was released on 2020-02-18 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectral lines, widths, and shapes are powerful tools for emitting/absorbing gas diagnostics in different astrophysical objects (from the solar system to the most distant objects in the universe—quasars). On the other hand, experimental and theoretical investigations of laboratory plasma have been applied in spectroscopic astrophysical research, especially in research on atomic data needed for line shape calculations. Data on spectral lines and their profiles are also important for diagnostics, analysis, and the modelling of fusion plasma, laser-produced plasma, laser design and development, and various plasmas in industry and technology, like light sources based on plasmas or the welding and piercing of metals by laser-produced plasma. The papers from this book can be divided into four groups: 1. stark broadening data for astrophysical and laboratory plasma investigations; 2. applications of spectral lines for astrophysical and laboratory plasma research; 3. spectral line phenomena in extragalactic objects, and 4. laboratory astrophysics results for spectra investigation. The reviews and research papers, representing new research on the topics presented in this book, are of interest for specialists and PhD students. We hope that the present book will be useful and interesting for scientists interested in the investigation of spectral line shapes and will contribute to the education of young researchers and PhD students.

Download or read book Springer Handbook of Atmospheric Measurements written by Thomas Foken and published by Springer Nature. This book was released on 2021-11-09 with total page 1761 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practical handbook provides a clearly structured, concise and comprehensive account of the huge variety of atmospheric and related measurements relevant to meteorologists and for the purpose of weather forecasting and climate research, but also to the practitioner in the wider field of environmental physics and ecology. The Springer Handbook of Atmospheric Measurements is divided into six parts: The first part offers instructive descriptions of the basics of atmospheric measurements and the multitude of their influencing factors, fundamentals of quality control and standardization, as well as equations and tables of atmospheric, water, and soil quantities. The subsequent parts present classical in-situ measurements as well as remote sensing techniques from both ground-based as well as airborn or satellite-based methods. The next part focusses on complex measurements and methods that integrate different techniques to establish more holistic data. Brief discussions of measurements in soils and water, at plants, in urban and rural environments and for renewable energies demonstrate the potential of such applications. The final part provides an overview of atmospheric and ecological networks. Written by distinguished experts from academia and industry, each of the 64 chapters provides in-depth discussions of the available devices with their specifications, aspects of quality control, maintenance as well as their potential for the future. A large number of thoroughly compiled tables of physical quantities, sensors and system characteristics make this handbook a unique, universal and useful reference for the practitioner and absolutely essential for researchers, students, and technicians.

The third chapter covers infrared magnetooptical spectroscopy in semiconductors and magnetic materials in high pulsed magnetic fields. Chapter 4 discusses spectral thermal infrared emission of the terrestrial atmosphere. Chapter 5 investigates frequency tuning and efficiency enhancement of high-power far-infrared lasers, while the last chapter discusses far-infrared laser scanner for high-voltage cable inspection. 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: A typical optical system is composed of three basic components: a source, a detector, and a medium in which the optical energy propagates. Many textbooks cover sources and detectors, but very few cover propagation in a comprehensive way, incorporating the latest progress in theory and experiment concerning the propagating medium. This book fulfills that need. It is the first comprehensive and self-contained book on this topic. It is useful reference book for researchers, and a textbook for courses like Laser Light Propagation, Solid State Optics, and Optical Propagation in the Atmosphere.
