(Left) 67Zn DFS-enhanced 3QMAS NMR spectrum of ZIF-4; (Right) experimental and simulated 67Zn 1D MAS spectra with two Zn sites at 18.8, 21.1 and 35.2 T. The total experimental time for 3QMAS experiment is 3 days and 4.5 hours. The acquisition times of the 1D 67Zn MAS spectra at 18.8, 21.1 and 35.2 T are 2.38, 10 and 1.25 hours, respectively.
