Hello,
I have tried H-F HOESY experiments previously and it worked. I used the
paper as a reference: Lithium Speciation in the LiPF6/PC Electrolyte
Studied by Two-Dimensional Heteronuclear Overhauser Enhancement and
Pulse-Field Gradient Diffusometry NMR | The Journal of Physical Chemistry C
<
https://pubs.acs.org/doi/10.1021/acs.jpcc.8b11599>
Our instruments are AV III HD 400 MHz with BBFO probe and it works well
using the LiPF6/PC electrolyte for testing. A battery research group
supplied this compound to me and they told me it is easy to make.
Hope this helps!
Best,
Fu
