Comments: The UV absorption spectrum of SO2 molecules in the range 190-436 nm has been investigated under various 
excitation conditions. The dependence on the temperature was measured in shock-wave experiments over the range 800-4000 K. 
The results are compared with spectra recorded after laser excitation at 248 and 308 nm.
