## Hartmann-Hahn cross-polarization transfers in liquids are used for correlating two J-coupled nuclei of different isotopic nature. It is explainedwhy continuous-wave spin-locking fields are difficult to use and have to be replaced by phase-modulated fields which compensate for inhomogeneity effe

Selective 1 H-13 C inverse NMR experiments based on heteronuclear cross-polarization (HCP) are presented. Practical details on the implementation of one-bond [ 1 J C,H ] optimized and pseudo-3D HCP experiments combined with gradient coherence selection are reported. On the other hand, accurate value
## Abstract Selective detection of {1β^13^C}βglucose and its glycolytic product, {3β^13^C}βlactate, was achieved by selective ^13^C NMR spectroscopy with ^1^H cross polarization. The total sensitivity of conventional broadband experiments was retained, and peak intensities were at least equivalent
