A method of assigning13C nuclear magnetic resonance spectra using europium(III) ion-induced pseudocontact shifts and C–H heteronuclear spin decoupling techniques

Abstract

We report a novel method for making ¹³C n.m.r. assignments using lanthanide ion-induced pseudocontact shifts in the ¹H spectrum to separate out the different absorptions and thus to facilitate the use of C–H selective heteronuclear spin decoupling experiments.
