From: Control of single-ligand chemistry on thiolated Au25 nanoclusters

Tandem mass spectra and corresponding fragmentation patterns of (a) [Au25MHA18] and (b) [Au25MHA19]0. (m, n) denotes species with molecular formula of AumSRn. Different routes are divided into major, minor, and trace categories based on the abundance in tandem mass spectra. See Supplementary Fig. 7 and 8 for detailed assignments of fragment species.
