High Resolution Molecular Spectroscopy of Atmospheric Species

Abstract

The pressure-broadening of the 2 (1,1 ) - 2 (1 2), 3 (1,3) - 2 (2,1 ) , and 7 (3,4) - 6 (4,3) transitions of HDO were studied between 90K and 600K. The broadening gases were He, H2, 02, and N2. Results for the temperature dependence of the pressure broadening parameters and collisional cross sections are discussed. The HDO transitions selected for study belong to widely different lower state energies. Such a selection allows to observe any dependence that 300K broadening parameters and temperature coefficients-may have on the rotational quantum numbers. All these have considerable theoretical interest.
