Study of Water Vapor Absorption Lines in the Near Infrared
Abstract
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.
