“…LF-NMR spectroscopy has been widely used to study the interactions between particles and solvents in suspensions based on the different relaxation behaviors of the solvents. The relaxation behavior can be understood using the rapid exchange of solvent molecules bound to particles and free solvent molecules. , The spin–spin relaxation times of the solvents were measured using the Carr–Purcell–Meiboom–Gill (CPMG) pulse sequence. The bound solvents exhibited relaxation times shorter than those of the free solvents.…”
