High Resolution Molecular Spectroscopy of Atmospheric Species. (The Pressure Broadening of HDO by O2, N2, H2, and He between 100 and 600 Deg K)
Abstract
Laboratory-based pressure-broadening data has long provided information that is both of practical importance for technological applications and of fundamental interest for understanding molecular interactions and dynamics. During this project period the temperature dependence of the collision-broadened line widths of H20 and HDO were studied between 100 deg K and 600 deg K. Selected transitions were between 250 GHz and 500 GHz and the broadening gases were 02, N2, H2, and He. Low temperature measurements were made in a collisionally cooled cell to circumvent the limitations imposed by the low vapor pressure of the sample gas at temperatures far below their freezing points. The experimentally determined values were compared with earlier experimental and theoretical works.
