Book Description
The purpose of this work was to develop a highly stable spin flip Raman laser that could be tuned through the 5 micron region in order to study water vapor absorption lines. The pressure broadening coefficients for various buffer gases when added to water was measured with this system. A general technique was devised to measure the shape of absorption lines well out onto the wings to determine if there were any deviation from a Lorentzian lineshape. In addition, theoretical work was done on the interaction of a radiation field with molecules undergoing a collision. A formulation was developed and used to treat the case of a collision between two noble gases.

Nu-averaged Infrared Absorption Coefficients of Water Vapor

Pages : 32
Book Description
We report the quantitative absorption coefficients of water vapor in a format suitable for calculation of water vapor absorption spectra characterized by instrumental bandpasses of 1 cm−1 or greater in the 670 to 1450 cm−1 region. The coefficients are derived from individual line parameters of H2O and represent a useful way of reducing line parameter data to a practical volume of information for 1 cm−1 resolution spectra of the troposphere. Transmission spectra for three water vapor concentrations show typical applications of the absorption coefficient tables. The application of the data is restricted to conditions within 10% of 1 atmosphere pressure and a temperature of 296 K if a transmission accuracy of 2% is to be maintained.
Tropospheric Water Vapor Absorption in the Infrared Window Regions

Book Description
Attenuation of infrared radiation in the troposphere is dominated by water vapor absorption. Most past work on the spectroscopy of water vapor has been on the analysis of the rotational and vibrational bands. As a result a thorough listing of line positions, line strengths and halfwidths exists today. Because of the weak 'continuum' absorption in the water vapor windows centered at 10 and 4 microns, efforts to measure and model the continuum have not been as successful as efforts in the analysis of the bands. Yet a precise understanding of continuum absorption is important for long path energy transmission. The purpose of this study is to demonstrate the importance of far wing phenomena in characterizing H2O continuum absorption. A total line shape for water vapor-nitrogen interactions valid under tropospheric conditions is derived. The model is tested using a set of experimental room temperature H2O continuum measurements of high quality. Using this data base parameters of the far wing component of the total line shape are determined.
