Therefore, there is an increasing interest in the study of the structure, properties and applications of these mixtures. In this paper, several NMR spectroscopic techniques have been used in order to evaluate the molecular structure of three ternary DESs, composed of choline chloride, urea or glycerol or ethylene glycol, and water. The use of routine and non-routine NMR techniques, such as 1H, 13C, correlation experiments, NOESY, ROESY, and diffusion experiments gave us some important evidences pointing to a supramolecular structure of the DES, which may be the origin of their particular behaviour. The mixture containing ethylene glycol shows the feeblest structure. In these ternary solvents, the water is found within the structure that is still retained when DESs are diluted at 10% wt. 000089886 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FEDER/E31-17R 000089886 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000089886 592__ $$a0.883$$b2019 000089886 590__ $$a5.065$$b2019 000089886 593__ $$aAtomic and Molecular Physics, and Optics$$c2019$$dQ1 000089886 591__ $$aPHYSICS, ATOMIC, MOLECULAR & CHEMICAL$$b4 / 36 = 0.111$$c2019$$dQ1$$eT1 000089886 593__ $$aCondensed Matter Physics$$c2019$$dQ1 000089886 591__ $$aCHEMISTRY, PHYSICAL$$b45 / 158 = 0.285$$c2019$$dQ2$$eT1 000089886 593__ $$aSpectroscopy$$c2019$$dQ1 000089886 593__ $$aMaterials Chemistry$$c2019$$dQ1 000089886 593__ $$aPhysical and Theoretical Chemistry$$c2019$$dQ1 000089886 593__ $$aElectronic, Optical and Magnetic Materials$$c2019$$dQ1 000089886 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000089886 700__ $$0(orcid)0000-0003-3632-6822$$aLafuente, Carlos$$uUniversidad de Zaragoza 000089886 700__ $$0(orcid)0000-0002-8354-7436$$aMuñoz-Embid, José$$uUniversidad de Zaragoza 000089886 700__ $$0(orcid)0000-0003-1810-9488$$aArtal, Manuela$$uUniversidad de Zaragoza 000089886 7102_ $$12013$$2765$$aUniversidad de Zaragoza$$bDpto.
