Title: Quantitative SO2 Detection in Combustion Environments Using Broad Band Ultraviolet Absorption and Laser-Induced Fluorescence

Journal/Source: Anal. Chem., 91, 16, 10849–10855, (2019); https://doi.org/10.1021/acs.analchem.9b02505


Data: table, diagram

Energy/Wavelength range: 230 - 350 nm

Resolution: 

Temperature: 1120 - 1950 K

Temperature dependence: yes

Pressure/Concentration: 

Phase: gas

pH: 


Comments: Spectrally resolved ultraviolet (UV) absorption cross sections of SO2 in combustion environments at temperatures from 1120 to 1950 K were measured.
The temperature was observed to have a significant effect on the absorption cross-section profiles at wavelength shorter than 260 nm, while at the longer wavelength 
side, the absorption cross-section profiles have much less dependence on temperature.
