Chemical Proton Shifts in H2O–D2O Solutions

Investigation of the high-resolution proton NMR spectra of water and aqueous solutions makes it possible to obtain additional information on their structure and on the nature of their intermolecular interactions. It is now thought that the displacement of the proton signal toward higher yield strengths when the temperature is raised is due principally to weakening or complete rupture of the hydrogen bonds [1, 2]. This affords new opportunities for selection of reliable models of the water structure [3–5]. It has been found that the best agreement with NMR data is achieved with the two-structure model [6–9].
