| Abstract: |
The ultrafast dynamics and dissociative ionization of CS2 were studied using the pump-probe method with time-of-flight mass spectroscopy. The transient behavior of both parent ion Due to image rights restrictions, multiple line equation(s) cannot be graphically displayed and fragment ions (S+ and CS+) was observed. It was found that all the ionic signals decay exponentially with lifetimes that were different for delay times, t>0 and t<0, which can be attributed to the evolution of different Rydberg states pumped by 267-nm and 400-nm laser pulses. The lifetimes of two Rydberg states were obtained simultaneously from one fitting of the transients. The fragment ions were produced by the dissociation of Due to image rights restrictions, multiple line equation(s) cannot be graphically displayed, and it is suggested that the final ionic state is the Due to image rights restrictions, multiple line equation(s) cannot be graphically displayed state of Due to image rights restrictions, multiple line equation(s) cannot be graphically displayed based on the measured S+/CS+ branching ratio. The S+/CS+ ratio is dependent on the delay time of the two lasers, indicating that the dissociation process of Due to image rights restrictions, multiple line equation(s) cannot be graphically displayed is related to the evolution of the intermediate Rydberg state.
