Fig. 2. Influence of 1H decoupling strength during an echo period (Fig. 1a). The
samples are 2 M 13C-urea (circles) and 0.1 M 13C-2-glycine (triangles) with 20 mM
TOTAPOL in d6-DMSO/D2O/H2O (6:3:1 by volume) in a 3.2-mm thin-wall zirconia
rotor. Open and filled symbols represent CW and SPINAL-64 decoupling,
respectively.
