Abstract

15N spin-lattice relaxation dynamics in metronidazole- 15N 3 and metronidazole- 15N 2 isotopologues are studied for rational design of 15N-enriched biomolecules for signal amplification by reversible exchange in microtesla fields. 15N relaxation dynamics mapping reveals the deleterious effects of interactions with the polarization transfer catalyst and a quadrupolar 14N nucleus within the spin-relayed 15N- 15N network.
