Abstract
Oxygen-17-detected DNP NMR of a water/glycerol glass enabled an 80-fold enhancement of signal intensity at 82 K, using the biradical TOTAPOL. The >6000-fold savings in acquisition time enable [superscript 17]O–[superscript 1]H distance measurements and heteronuclear correlation experiments. These experiments are the initial demonstration of the feasibility of DNP NMR on quadrupolar [superscript 17]O.
