Finally, 13C-NMR with cross-polarization and magic angle spinning (13C-CP/MAS) has been used to examine changes in the mesomorphic states of phospholipids at various temperatures in the absence and presence of the two drugs. Three effects were followed ...

The cross polarization, or CP, process may be used with any or all of the line narrowing techniques to obtain NMR spectra of solids with resolution approaching that of liquids ). A combination of cross polarization (CP), magic angle spinning (MAS) and dipolar decoupling were used to obtain the spectrum of a very insoluble polyphenylene sulfide (Ryton) as shown in Fig. 6. 

The structure of SDS and CTAB surfactant layer adsorbed on porous silica was studied by NMR. The C18 (Microsorb ODS, 5 pm, 6 nm pore diameter) and C8 (Microsorb) bonded phases were studied first [17]. The cyanopropyl bonded phase (Microsorb), was also studied [18]. Cross polarization (CP), magic angle spinning (MAS) with high power proton...
