We show how DNP enhanced solid-state NMR spectra can be dramatically simplified by suppression of solvent signals. This is achieved by (i) exploiting the paramagnetic relaxation enhancement of solvent signals relative to materials substrates, or (ii) by using short cross-polarization contact times to transfer hyperpolarization to only directly bonded carbon-13 nuclei in frozen solutions. The methods are evaluated for organic microcrystals, surfaces and frozen solutions. We show how this allows for the acquisition of high-resolution DNP enhanced proton-proton correlation experiments to measure inter-nuclear proximities in an organic solid.

[Question from NMRWiki Q&A forum] How can I tell if and what kind of solvent suppression was used?
How can I tell if and what kind of solvent suppression was used?
I have some older 2D HSQC 1H-15N data that was run by a NMR tech. Is there a way I can tell what kind of solvent suppression was used by looking through the acquisition files? Like I know I can open them up as text documents and see a lot of the experimental parameters, but I don't know if solvent suppression is listed in one of those parameters.
Thanks! -Brian W.

Simultaneous convection compensation and solvent suppression in biomolecular NMR diffusion experiments
Simultaneous convection compensation and solvent suppression in biomolecular NMR diffusion experiments
Abstract Thermal convection and high intensity solvent resonances can significantly hamper diffusion estimates in pulsed gradient spin-echo nuclear magnetic resonance diffusion experiments on biomolecule samples. To overcome these two problems, a new double functional NMR diffusion sequence, double echo PGSTE-WATERGATE, is presented. The new sequence provides excellent convection compensation and solvent suppression (with a suppression factor in excess of at least 105 in a single scan)...
