Static 31P spectra of (a) hydrated POPC and (b) lyophilized POPC with 20% trehalose. (c) Temperature dependence of the 31P chemical shift anisotropy parameter δ for hydrated POPC (open squares) and TRE-POPC (filled squares). (d) Temperature dependence of the 31P chemical shift asymmetry parameter η for hydrated POPC (open circles) and TRE-POPC (filled circles).
