Abstract

Pressure broadening cross sections for the $2_{2,0}\leftarrow 2_{1,1}$ rotational transitions of hydrogen sulfide ($H_{2}S$) in collison with hydrogen ($H_{2}$) have been measured between 12 and 500 K. Measurements below 40 K were made using the collisional cooling technique, while measurements at higher temperatures were made in an equilibrium cell. Comparisons of these data with earlier measurements of the $1_{1,0}\leftarrow 1_{0,1}$ transition will be made as well as comparisons to measured cross sections of hydrogen sulfide in collision with helium (He). The data analysis techniques and experimental apparatus are described.
