Binding energy distributions and binding modes for ten N- and S-bearing species on the 15 ASW₁₂ clusters, ordered from the most strongly to the most weakly bound. The solid black curves show fits to the full BE distributions, characterized by μ_tot and σ_tot. Where a distinct secondary binding mode is present, its fit is shown by a dashed black curve and characterized by μ_sec and σ_sec. All binding energies are given in K.
