Figure 3

Experimental 1H-magic-angle-spinning NMR spectra for (a) C12A7:H− (red line) and C12A7:OH− (blue line), and (b) S12A7:H− (red line) and S12A7:OH− (blue line) samples, and corresponding theoretical spectra for (c) C12A7 and (d) S12A7 systems. Broad signals between +7 and −2 p.p.m. in the experimental spectra of S12A7 are attributed to adsorbed water and hydroxide impurities.
