Fig. 1: Proton NMR spectra and chemical shift changes in ChCl and glycerol mixtures.
From: Evolution of microscopic heterogeneity and dynamics in choline chloride-based deep eutectic solvents
a 1H NMR spectra of glycerol and mixtures of 5, 10, 20, and 33 mol% ChCl in glycerol at 333 K. Purple letters a–f denote the various protons on glycerol (left chemical structure) and ChCl (right chemical structure). b Change in chemical shift in ppm with respect to neat glycerol as a function of ChCl concentration. Letters a–e denote the protons as specified in purple in part (a).
