The interaction of water with poly(ethylene glycol) and oligo(ethylene glycol) moieties in alkanethiolate SAMs is strongly dependent on the molecular conformation, lateral density and external electrical fields. In this contribution we will present ab initio quantum mechanical results and Monte Carlo Simulations on the ethylene glycol / water interaction and correlate them with vibrational sum frequency generation spectroscopic results of the OEG / water interaction,@footnote 1@ force distance measurements between neutral and charged AFM tips and OEG SAMs of different density,@footnote 2@ and single molecule force spectroscopy.@footnote 3@ @FootnoteText@ @footnote 1@M.
