High Resolution Molecular Spectroscopy of Atmospheric Sciences
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 18(3,15)- 18(2,16), 4(2,2)-3(1,3), 13(1,13)- 12(0,12), and 26(4,22)- 26(3,23) transitions of SO2 at 204.246 GHz, 235.151 GHz, 251.199 GHz, and 280.807 GHz respectively, and 1(1,0)-1(0,1) and 2(2,0) - 2(1,1) 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.
