Comments: Using synchrotron radiation as a continuum light source, we have measured the absolute photoabsorption cross sections 
of H2S from 1600 to 2600 Å under temperature conditions of 370, 295, and 170 K and a spectral bandwidth (FWHM) of 0.6 Å. Moderate 
temperature effects are observed in the 1850–2100 Å and the absorption threshold regions. The peak, 1609.4 Å, which is assigned to a 
hot band transition shows pronounced temperature effect.
