Book Description
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.
