THE 1550-1460 ANGSTROM REGION OF CS2

The 1550-1460 Angstrom region of CS2 has been investigated by both (11')+1 and (3+1) resonance enhanced multiphoton ionization and the spec tra obtained compared to previous one photon and electron impact studi es. The results of this study indicate that the main feature in this r egion is due to an optically allowed transition to either a (IIu)-I-1 valence state or a (1) Sigma(u)(+) Rydberg-valence type state and that this state is strongly predissociated. There is also evidence of gera de valence states in this region but there is no evidence of gerade Ry dberg states. (C) 1996 American Institute of Physics.
