It is known that the proton magnetic resonance spectrum (NMR 1H) ethyl alcohol consists of multiplets from CH3, CH2- groups and signal OH- groups of alcohol. When adding water to alcohol in the NMR spectrum1In the mixture “alcohol + water”, a water signal appears, located next to the signal of the OH-groups of alcohol. With an increase in the concentration of water in the “alcohol + water” mixture, the signals of
water and OH-groups of alcohol first broaden and then merge into one total signal. Such changes in the signals of water and OH-groups of alcohol in a mixture “alcohol + water” are due to proton exchange between water molecules and OH-groups of
alcohol, and this exchange occurs by a barrier mechanism (tunnel effect).
