a A magnetic field of 3 T overcomes spin‒orbit coupling. b Induced magnetic moment vs. temperature of the ZnSO4 electrolyte magnetized in a perpendicular magnetic field of 3 T. c Dipole moments (T = 298 K) of the ZnSO4 electrolyte magnetized in a perpendicular magnetic field of 3 T. d Diverse water coordination structures and ion interactions in the ZnSO4 aqueous electrolyte. e Magnetic field (3 T)-induced enhancement of the symmetric O–H stretching vibration. f Magnetic field intensity-dependent population of hydrated ions according to the Raman spectra. g 1H NMR spectra of the magnetized ZnSO4 electrolyte. h Normalized 17O NMR spectra of the magnetized ZnSO4 electrolyte. i 17O NMR spectra of neat D2O and the electrolyte showing (inset) a new peak at −70 to −30 ppm in the electrolyte that corresponds to SO42−–H2O. j Magnetic field intensity dependence of H3O+, where r, a, and b represent the frustrated rotation, asymmetric O–H stretching, and H–O–H bending of H3O+, respectively.
