Photoionization dynamics in CS fragmented from CS2 studied by high-resolution photoelectron spectroscopy

Article abstract of DOI:10.1139/v04-015

The photoionization dynamics of CS have been studied using high-resolution laser photoelectron spectroscopy. The photodissociation of CS₂ at ～308 nm results in highly rotationally excited CS in its X ¹∑⁺ singlet ground state, as well as in rotationally cold CS in the excited a³Π triplet state. The ground-state CS fragments are formed together with sulfur in its ³P, ¹D, and ¹S electronic states; triplet CS is produced in coincidence with ground-state sulfur (³P). In both channels the photoelectron spectra are dominated by Δν = 0 propensity, but transitions involving Δν = 1 and 2 are also observed.
