Abstract
The photoabsorption spectrum of the CS2 molecule has been recorded in the vicinity of the two S2p3/2,1/2 ionization limits at 169.806 eV and 171.075 eV. Synchrotron radiation was used with photon energies covering the energy range between 160 eV and 175 eV. Extensive structure is observed below the ionization limits. It is associated with transitions to both valence and Rydberg states. The latter contain vibrational fine structure due to excitations of the ν3 asymmetric stretching mode. The vibrational energy is approximately 195 meV in close agreement with previous results obtained from photoelectron spectra for the S2p3/2,1/2 single-hole states. Above the ionization limits, a resonance is observed in the ionization continuum. An electron spectrum recorded on top of this resonance reveals S2p−1 VV Auger transitions at high resolution.
