✦ Synopsis
Abstract
The 1D‐TOCSY experiment for ^2^H NMR is introduced and applications for signal assignments are illustrated with the spectra of pyridine‐d~5~ and iodo‐ and chlorocyclohexane‐d~11~. The potential of the method for the analysis of overlapping ^2^H spectra is demonstrated.

We have prepared RNAs uniformly 13C-labeled in the ribose ring and with the H3',H4',H5'/H5" protons specifically replaced with deuterons (3',4',5'/5"-2H-13C, termed d4-13C ribose), which offers the advantage of spectral simplification without sacrifice of sensitivity for the remaining protons. A 3D
After correlation of the majority of signals by COSY and one-bond heteronuclear correlation, the complete assignment of the 'H and I3C NMR spectra of the macrolide antibiotic venturicidin A required the application of long-range CH coupling information. This was accessible by the COLOC-S and selecti
