Minimum labelling: 13C

Dimensions: 2

The magnetisation is transferred from 1H to 13C and then back again for detection and all 1H-13C moieties, regardless of chemical type, are observed.

13C-HMQC magnetisation transfer

This is the carbon equivalent of the 1H-15N-HSQC. All H-C correlations are shown. It can be useful as a basis for picking a 3D 13C NOESY spectrum. It can also be a useful reference for the aromatic peaks.
