Abstract: | Single and multiple photon processes are identified in the 193 nm excimer laser photolysis of CS2. CS(X1Σ+, υ = 1 to 5, J = 5 to 45) is observed by dye laser induced fluorescence of the A1Π ? ; X1Σ+ transition, following the single photon 193 nm photolysis of CS2. Multiple photon 193 nm generation of CS fragment emission from 620 to 170 nm is also reported. A partial assignment of the emission spectrum identifies fluorescence from the CS A′1Σ+ and A1Π states. |
