1H NMR spectra (35°C) of positively magnetically aligned bicelles as a function of the field-gradient pulse amplitude in the STE PFG NMR sequence. Bicelle composition was as per Fig. 3q = 4.5. The stimulated echo delay in this case was 400 ms. The water resonance is at 4.5 ppm while the resonance at 3.3 ppm is due primarily to the free PEG 2000.
