Figure 5
Solid-state 13C CP/MAS (column A) and 23Na (column B) MAS NMR spectra measured at 313 K. Resonance assignments are shown for AH and MH (labelling according to Scheme 1[link]). The assignments for DH-I and DH-II are clear by analogy. Spectra are also shown for sodium ibuprofen dihydrate (top), which has a similar structure to DH-II in the Na+/H2O region (see text).
