Title: HIGH, ROOM AND LOW-TEMPERATURE PHOTOABSORPTION
CROSS-SECTIONS OF CS2 IN THE 1800-2300-ANGSTROM REGION

Abstract: 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 Angstrom. The
absorption cross sections of CS2 have been measured from 1800 to
2300 Angstrom at temperatures of 383 and 295 K and from 1800 to
2150 Angstrom 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 Angstrom 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
