Title: Experimental study on the temperature dependence of ultraviolet absorption cross-sections of sulfur dioxide

Journal/Source: Frontiers of Energy and Power Engineering in China, 2 (2), 183-186, (2008); DOI:10.1007/s11708-008-0025-2


Data:  

Energy/Wavelength range: 200 - 230 nm; 275 - 315 nm

Resolution: 0.2 nm

Temperature: 298 - 415 K

Temperature dependence: yes

Comments: The photoabsorption cross-sections of sulfur dioxide were measured in the spectral regions of 200-230 nm and 275–315 nm at 298-415 K.
The absorption cross-section peaks decreased linearly when the temperature increased from 298 to 415 K, with relative drops of 74% and 75.8%
at 200-230 nm and 275-315 nm.
