Figure 2

Solid-state 2H NMR de-Paked spectra in the liquid-crystalline (liquid-disordered or Lα) state at T = 35°C for DMPC-d54 bilayers showing the effect of (a) different amounts of hydration water and (b) various concentrations of osmolyte poly(ethylene glycol) Mr 1500 (PEG 1500). In both cases, the quadrupolar splittings (peak-to-peak splitting) ΔνQ(i) change due to removal of water from the interlamellar space.
