Manganese polysulfide cations, MnSx+(x= 1–10), were studied with mass-selected photodissociation experiments and density functional calculations. We found that MnS+, MnS2+and MnS3+undergo dissociation at 355 nm by loss of S, S2and S3, respectively. The dissociation of larger clusters is relatively complex because of the existence of multiple isomers and multiple dissociation channels. The geometric structures of the low-lying isomers found by theoretical calculations are consistent with the dissociation channels observed in the experiments. The dissociation of MnSx+clusters occurs mainly by breaking of the Mn–S bonds since they are weaker than the S–S bonds. [ABSTRACT FROM AUTHOR] |
