Abstract:

During this project period the temperature dependence of the collision-broadened line widths of few selected lines of SO2 and H2S were studied between 90 K and 600 K. Selected lines were 183,15- 182,16, 42,2-31,3, 131,13- 120,12, and 264,22- 263,23 transitions of SO2 at 204.246 GHz, 235.151 GHz, 251.199 GHz, and 280.807 GHz respectively, and 11,0-10,1 and 22,0 - 21,1 transitions of H2S at 168.762 GHz and 216.710 GHz respectively. The broadening gases were N2, O2 , H2, and He. Reported pressure broadening results of SO2 and H2S extends for the first time to such a wide range of temperature. The newly developed Fast Scan Submillimeter Spectroscopic Technique FASSST was applied to investigate HNO3. A brief description of the system and some preliminary results related to HNO3 are included in the text below.
