Abstract

By introducing a range of ²H labels into pyridine and the para-substituted agents, methyl isonicotinate and isonicotinamide, we significantly improve their NMR detectability in conjunction with the signal amplification by reversible exchange process. We describe how the rates of T₁ relaxation for the remaining ¹H nuclei are increased and show how this leads to a concomitant increase in the level of ¹H and ¹³C hyperpolarization that can ultimately be detected.
