Using synchrotron radiation as a continuum light source, we have measured the absolute photoabsorption cross sections of CS2 with a spectral bandwidth (FWHM) of 0.8 ¿. The absorption cross sections of CS2 have been measured from 1800 to 2300 ¿ at temperatures of 383 and 295 K and from 1800 to 2150 ¿ at 203 K. Significant temperature effects and hot bands are observed, particularly in the long wavelength region. The apparent continuum cross section underlying the vibrational features in the 2200--2300 ¿ region increases by about an order of magnitude when the gaseous CS2 temperature increases from 295 K to 383 K. The new temperature-dependent laboratory cross section data should be useful in the determination of the CS2 abundance in Jupiter's atmosphere after the impact of Comet Shoemaker-Levy 9. ¿ American Geophysical Union 1995
