Fragmentation habit of Au@Ag nanoclusters. a Tandem mass spectra and b schematic illustration of fragmentation process of Au-core/Ag-shell [Ag40Au4(SR)30]4− (centered at m/z = 2424; SR denotes thiolate ligand) obtained at different collision energies. Insets of a are zoom-in spectra of the boxed area in the corresponding panels. The orange, blue and purple arrows in b indicate the fragmentation pathways by dissociation of SR−, [Ag(SR)2]−, and [Ag2(SR)3]−, respectively
