Book Description
The true shape of the rotational absorption lines of the hydrogen fluoride fundamental band was investigated. The line shapes were to be measured at pressures where pressure broadening made the only significant contribution to the true line shape. The experimental aspects of this investigation are discussed. All data were taken with the vacuum-grating spectrograph recently completed at the University of Tennessee. The results of the line center and line shape measurements are presented. Twentyone fundamental and seventeen first overtone line centers were measured at low pressure with an estimated accuracy of! 1/0.02 cm. The fundamental and first overtone band centers were calculated to be 1/3961.43 cm and 1/7750.83 cm, respectively. The results of this investigation and suggestions for future experiments in this field are presented.

Book Description
The aim of this investigation was to determine experimentally the true line shape and line position for as many as possible of the high J rotational absorption lines in the hydrogen fluoride fundamental band. The line shapes were to be determined at identical temperatures and at pressures where pressure broadening made the only significant contribution to the line shape. All data were taken on the high resolution vacuum-grating spectrometer. The HF lines were used as internal standards for calibrating purposes. The R(5) line of the first overtone of CO was used to determine the slit function to correct measured line shapes for distortions caused by instrumental broadening. The line position of R(11) was measured to be 4320.97 waves per cm. The line shapes of R(9), R(10), and R(11) were determined and found to be truly Lorentzian.

Spectroscopy of the earth's Atmosphere and interstellar Medium

Pages : 539
Book Description
Spectroscopy of the Earth's Atmosphere and Interstellar Medium focuses on the characteristics of the electromagnetic spectrum of the Earth's atmosphere in the far-infrared and microwave regions. It discusses the modes of observation in field measurements and reviews the two techniques used in the spectral region. Organized into six chapters, this volume begins with an overview of the effect of water-vapor absorption, followed by a discussion on the two frequently used method for deriving atmospheric parameters from high-resolution infrared atmospheric spectra, namely, the equivalent width (EW) technique and the nonlinear least-square fitting (NLSF). Other chapters consider the mechanisms by which interstellar clouds are formed. In addition, the book explores the composition of interstellar clouds, ion-molecule reactions, and the formation of stars. This book will be useful to anyone involved in, or interested in learning more about the field of atmospheric spectroscopy, including scientists, aeronomers, astronomers, astrophysicists, and students.
