TLDR
Sum frequency generation (SFG) vibrational spectra of D(2)O and/or acetonitrile on a Pt(111) single-crystal electrode were obtained and provide a very specific model for the composition of the inner Helmholtz layer as a function of potential and surface charge.Abstract:
Sum frequency generation (SFG) vibrational spectra of D2O and/or acetonitrile (CH3CN) on a Pt(111) single-crystal electrode were obtained as a function of applied potential in a 5 mol % water/aceto...read more
