摘要: Abstract A reflectron-time-of-flight mass spectrometer (RTOFMS) coupled with a femtosecond multiphoton ionization technique is used to study the combined metastable and collision-induced dissociation of sulfur dioxide clusters mixed dioxide-water clusters. From patterns, general structural arrangement clearly identified: (SO2)m·+ have SO2·+ core solvated by SO2 molecules; [SO(SO2)n]·+ [S(SO2)n+1]·+ structure SO·+ · (SO2)n (SO)2·+ (SO2)n, respectively. For [HSO2(SO2)]+ clusters, ion HSO2+. H3SO3+ appears two isomeric structures: one HSO2+ H2O, other H3O+ SO2.
