Figure 4

CID breakdown curves of [H3Mo3S13]+ showing the sum-intensities of thiomolybdate [HxMo3Sy]+ and thio-oxo-molybdate [HxMo3SyOz]+ clusters, denoted as Thio and Thio-Oxo respectively. Increased reactivity toward water is observed at high collision energies (Vc > 22 V), indicating a high activation barrier. Reactions with water are assigned to residual humidity inside the collision gas inlet.
