Structural relatedness between Au23 and Au25 nanoclusters. a,b Tandem mass spectra and c,d fragmentation pathways of a,c [Au23(SR)16]− and b,d [Au25(SR)18]−. SR denotes thiolate ligand. For clarity purpose, the cluster and fragment cluster ions [Au n (SR) m  + x Na – (x + y) H]q’ are referred to as (n, m, y)q’. The applied collision energies are indicated at the left-top corner of each spectrum in a,b, while the inset in each row shows boxed area in the corresponding spectrum. The abundance order of the fragment cluster ions is summarized underneath the corresponding ions, whereas the dominant fragmentation pathways are highlighted by the magenta arrows
