doi: 10.1063/5.0158608

Figure Lengend Snippet: (a) Radio frequency pulse sequence used for creating, filtering, and detecting SQCs of 23 Na + in uniformly stretched and compressed hydrogels. (b) DQF and (c) TQF 23 Na spectra. Black solid line: experimental spectra; blue solid line: simulated spectra. Spectra were simulated using the Mathematica -based NMR software package SpinDynamica . Simulation parameters: S 0 * = 4.6 × 10 −3 , ω Q /2 π = 84.5 kHz, and τ C = 1.72 ns.
