AbstractAbstract
[en] Multipulse NMR techniques have been used to investigate the dynamic jproperties of cesium perfluoro-octanoate (CsPFO) and ammonium perfluoro-octanoate (APFO) + water systems, which are liquid crystals, over a wide range of temperautre and concentration. Axially symmetric fluorine chemical shift tensors have been measured for the CF2 and CF3 groups by performing a rotation study of an aligned sample (50% CsPFO : 50% D2O) at room temperature. The order parameter S in the lamellar mesophase of 72,2% CsPFO : 27,8% D2O and 70% APFO : 30% D2O has been obtained over as temperature range 200C - 850C by fitting the multipulse spectra. (author)
