Chemical shifts of the coalesced hydroxy proton magnetic resonance signal and departures from ideality in aqueous alcohol mixtures. I. The tert-butanol-water system

Maximum downfield chemical shifts of the coalesced hydroxy proton signal, relative to that predicted for an ideal solution, occurred at tert-butanol concentrations for which thermodynamic properties suggest the highest degree of water structuring. Shifts in the opposite direction reached extreme val...

Description
Summary:Maximum downfield chemical shifts of the coalesced hydroxy proton signal, relative to that predicted for an ideal solution, occurred at tert-butanol concentrations for which thermodynamic properties suggest the highest degree of water structuring. Shifts in the opposite direction reached extreme values near the azeotropic composition of the tert-butanol-water system.
