【 摘 要 】

Three body fragmentation pathways of OCS3+molecular ion leading to detection of C++O++S+in coincidence have been studied using the technique of recoil ion momentum spectroscopy. This fragmentation can occur either via a one step concerted process or a two step sequential process. In the first step of the sequential pathway either CO2+or CS2+is formed. By separating the events coming from the two processes, branching ratios are determined and the possible electronic states associated with the intermediate CO2+or CS2+have been identified.
