Comments: A heated and pressurized quartz cell with 150.5-mm pathlength was used to experimentally determine UV absorption spectra 
and further absorption cross sections of SO2, C2 H2, and O2 in the wavelength range between 200 and 400 nm. Spectra were recorded at 
room temperature, and at 600 and 800 C and at absolute pressures between 1 and 6 bar.
