  • The diffusion of protons close to membranes differs from bulk water due to interactions with the membrane. Here, the authors use DFTB3 simulations to clarify that while single protons bind to the membrane, others diffuse in the membrane’s hydration layers faster than in bulk water.

  • Proton migration on membranes is a crucial step in the bioenergetics of the cell. It has typically been regarded as slow successive proton transfers between ionizable moieties within the membrane, but recent measurements suggest fast lateral diffusion in the membrane's hydration layer.

  • While there is some qualitative understanding of how excess protons behave in acidic aqueous solutions, there is still much to learn about the structures they form with water molecules. Now, 2D infrared spectroscopy has enabled the definite identification of the 'Zundel cation' in protonated liquid water and an approximate determination of its lifetime.

  • The infrared spectra of gas-phase protonated water clusters and protonated liquid water have been calculated from molecular simulations using a ‘clusters-in-liquid’ approach, which is restricted to a selected set of charged atoms. The infrared absorption due to the central proton in the H2O···H+···OH2 moiety is found near 1,740 cm−1.
