Figure 6.

Mass spectra measured at the designated points of the dynamical depth profile displayed in Figure 5. The data were taken with the HCl doped Ar₂₀₀₀ GCIB at 110 K under simultaneous flooding with D₂O at different partial pressures. The three displayed peak groups correspond to the [M_n*−OH]⁺, [M_n* + H/D]⁺, and [M_n* + Na]⁺ (for the definition of M_n* see Figure 4) secondary ion signals
