Products of the laser multiphoton dissociation of carbon disulfide have been studied by mass-selected resonance-enhanced multiphoton ionization spectroscopy between 330 and 280 nm. Photolysis is shown to produce CS in its a/sup 3/II state, atomic carbon in its /sup 3/P, /sup 1/D, and /sup 1/S states, and sulfur in its /sup 3/P, /sup 1/D, and /sup 1/S electronic states. The results indicate that fragmentation of CS/sub 2/ competes with ionization at moderate laser flux densities and that fragmentation typically precedes ionization in the formation of fragment ions. Doppler broadening measurements indicate that little of the excess energy of photolysis is released as translational energy.
