英文摘要	On a home-made crossed ion-molecular beam tandem time-of-flight mass spectrometer, carbon cluster ions with two hetero-atoms, CnSH +/- and CnS2 +/-, were produced from laser ablation, mass-selected, and collided with pulsed nitrogen beam. From mass analysis of the fragment ions, structures of the cluster ions were characterized as linear, with two hetero-atoms locating on both ends of the carbon chain. The experimental results also revealed the main dissociation channel of the cluster ions. According to the results, for most cluster ions studied in the experiment, the weakest bond is the C-C bond next to the sulfur atom, but in some smaller cluster ions, S-C bond is easier to break. Under the experimental condition, cluster ions may suffer multiple collisions, so fragment ions produced from stepwise dissociation process were observed.
