Understanding the role of temperature in structural changes of choline chloride/glycols deep eutectic solvents

Anion dynamics and motional decoupling in a glycerol–choline chloride deep eutectic solvent studied by one- and two-dimensional 35Cl NMR

“…To study the mobilities of these components 1 H, 19-23 2 H, 24 13 C 25 and other nuclides 26 were exploited as probes. Even the 35 Cl nuclide (which is three times more abundant than 37 Cl) was already used, however, barely to unravel dynamical properties of DESs, 27 but mostly to monitor hydration-induced chemical shifts. [28][29][30][31] The rare exploitation of the 35 Cl resonance is probably due to the fact that for halide ions spin relaxation times can become fairly short (down to the ms regime).…”
