Hi Wendy,
I use a solution of LiCl in D2O. But be aware of the long T1 (30+ seconds).
I often add a trace of CuSO4. That brings the T1 down to ~ 1 - 2 seconds and
turns the solution the color of Mountain Dew.

Hi,
Does anyone have a recommendation for a compound to use to calibrate a 7Li
90-degree pulse?
TIA,
Wendy
