Did you run a saturated lead nitrate/D2O sample. You should be able to see
it with a few scans. It is easy to observe. You can pulse faster
(interpulse delay~ 0.5 sec). The proton coupling constants (~2500 Hz) and
chemical shift ranges(~9k ppm) are large. Proton decoupling may help boost
S/N. Good Luck.
