Abstract

We investigate the utility of “pure shift” techniques in revealing heteronuclear couplings in complex 1H NMR spectra. The results show the technique to be a robust and valuable complement to the standard 1H spectrum, and an attractive alternative to heteronuclear decoupling since the technique is independent of the size of the heteronuclear couplings and the chemical shift range(s) of the heteronuclei involved. We highlight some possible artefacts, and the subtle effects due to the presence of 13C nuclei in otherwise symmetric molecules when bilinear rotational decoupling (BIRD) elements are present in the pulse sequence.
