Photoionization dynamics in CS fragmented from CS2 studied by high-resolution photoelectron spectroscopy
The photoionization dynamics of CS have been studied using high-resolution laser photoelectron spectroscopy. The photodissociation of CS2 at similar to308 nm results in highly rotationally excited CS in its X(1)Sigma(+) singlet ground state, as well as in rotationally cold CS in the excited a(3)Pi triplet state. The ground-state CS fragments are formed together with sulfur in its P-3, D-1, and S-1 electronic states; triplet CS is produced in coincidence with ground-state sulfur (P-3). In both channels the photoelectron spectra are dominated by Deltav = 0 propensity, but transitions involving Deltav = 1 and 2 are also observed.

Abstract
The photoionization dynamics of CS have been studied using high-resolution laser photoelectron spectroscopy. The photodissociation of CS2 at similar to308 nm results in highly rotationally excited CS in its X(1)Sigma(+) singlet ground state, as well as in rotationally cold CS in the excited a(3)Pi triplet state. The ground-state CS fragments are formed together with sulfur in its P-3, D-1, and S-1 electronic states; triplet CS is produced in coincidence with ground-state sulfur (P-3). In both channels the photoelectron spectra are dominated by Deltav = 0 propensity, but transitions involving Deltav = 1 and 2 are also observed.
