Title: THE VARIABLE TEMPERATURE PRESSURE BROADENING SPECTRUM OF CO ON HYDROGEN
Creators: Flatin, D. C.; Goyette, T. M.; De Lucia, Frank C.
Issue Date: 1994
Abstract: A system has been developed which has allowed us to measure the hydrogen pressure broadening parameters of $CO, H_{2}S$, and $CH_{3}F$ between approximately 5K and 100K. In combination with other experimental system, this has allowed measurements over a 5K to 1000K range. In the semiclassical region above $\sim 100$K, the behavior of the cross sections for collision with hydrogen in more complex than comparable collisions with helium because of the additional rotational degrees of freedom in the hydrogen molecule. At low temperatures very significant increases in cross section, which are associated with the quasibound states, are observed. New results for CO hydrogen broadening will be discussed. Some comparisons will be made with measurements of other molecular systems. The apparatus will be described as will experimental results and their relationship to theoretical predictions.
