Handbook of High Resolution Infrared Laboratory Spectra of Atmospheric Interest (1981)
Author: Aaron GoldmanPublisher: CRC Press
ISBN: 1351363050
Category : Science
Languages : en
Pages : 266
Book Description
The handbook presents spectra to be utilized for the detection and measurement of new constituents in the earth's atmosphere and to obtain data for common minor species with large gas amounts in the absorption cell (such as CH/sub 4/ and N/sub 2/O). These results can be applied in the identification of absorption features in atmospheric spectra determined over long atmospheric paths. The spectra were recorded with Fourier Transform Spectrometers which are more precise than grating spectrometers. Each molecule spectrum was plotted on two scales: a condensed scale covering the range from 75 to 300/cm in one frame, and an expanded view covering 20 or 10/cm per frame. Each plot contains the name of the molecule, chemical formula, the gas pressure, cell length, and estimated resolution of the spectrum.

Infrared Methods for Gaseous Measurements
Author: WormhoudtPublisher: CRC Press
ISBN: 9780824774295
Category : Technology & Engineering
Languages : en
Pages : 312
Book Description
This interdisciplinary volume is an excellent resource for anyone who wants an in-depth understanding of current and emerging trends in gaseous measurement techniques. It provides both qualitative and quantitative introductions to the physics involved in using remote observations to collect data, and offers numerous examples that encourage new applications of existing technologies. Compiled by an authority on spectroscopy, chemical kinetics and infrared emissions from combustible sources, this volume compares burnoff flare and stack plume emission spectra with parametric calculations performed with equally high spectral resolution ... discusses sensitivity of spectra to source temperature, and behavior of emission and absorption linewidths with temperature ... reviews the emission-absorption techniques for determining temperature and species concentration profiles ... and much more. Infrared Methods for Gaseous Measurements is a vital research tool for photo-optical instrumentation engineers; electro-optical engineers; chemical, aerospace, automotive, combustion, environmental, and mechanical engineers; and technologists involved in radiation, infrared or laser research. The book also serves as an excellent resource for graduate molecular spectroscopy courses and postgraduate infrared technology seminars. Book jacket.
High Resolution Infrared Spectroscopy of Carbon Dioxide and Nitrous Oxide at Elevated Temperatures

Book Description
Although both Carbon Dioxide and Nitrous Oxide are minor constituents of the terrestrial atmosphere, they play leading roles in several current atmospheric problems. Both CO2 and N2O are greenhouse gases, and while it is known that the atmospheric concentrations of both gases is increasing, the impact of these trends on global temperature is not yet adequately understood. In addition to being a greenhouse gas, N2O plays an indirect part in ozone chemistry. Heating a molecule makes possible the observations of molecular transitions originating from highly excited rotation-vibration states. Heating a molecule makes possible the observations of molecular transitions originating from highly excited rotation-vibration states. These observations can then be used to characterize the shape of the molecular potential function at increasing distances from the minimum of the potential function. The infrared spectra of linear molecules like CO2 and N2O are composed of vibration bands made up of a number of nearly equally spaced rotation lines. A Fourier Spectrometer is ideally suited to the study of high temperature gases since it meets both of these needs by providing high resolution over a wide spectral region.

Book Description
Remote sensing of atmospheric gases improves our understanding of the state and evolution of the Earth's environment. At the beginning of the thesis, the basic principles for the retrieval of concentrations of atmospheric gases from spectra are presented with a focus on ground-based observations. An overview of the characteristic features of different platforms, viewing geometries, measurement sites, and Fourier Transform Spectrometers (FTSs) used in the measurements are provided. The thesis covers four main projects.
