Abstract

The 1H NMR spectra in a binary aqueous triethylamine solution are recorded with a lower critical point of the liquid–liquid phase transition. It is found that, above the critical temperature the 1H NMR spectra of water and triethylamine molecules in the phase with a predominant content of triethylamine molecules are characterized by an inhomogeneous broadening. It can be supposed that the found broadening is due to the features of the molecular distribution at the interface.
