✦ Synopsis

A new experiment, HETGOESY, is described in which "C-'H NOE enhancements are detected directly on 'H. The experiment uses pulsed field gradients for coherence selection, thus completely avoiding the problems associated with difference spectroscopy. It is shown, both theoretically and experimentally, that the new experiment has sensitivity advantages over the conventional I3C{ 'H} steady-state NOE difference experiment. The new experiment also has the advantage that it uses selective excitation in the generally better resolved decoupled I3C spectrum rather than the 'H spectrum.

## Abstract In the chemistry literature it is common to provide NMR data on both proton and carbon spectra based on one‐dimensional experiments, but often only proton spectra are assigned. The absence of a complete attribution of the carbons is in good part due to the difficulty in reaching the nec

One-dimensional heteronuclear NOE difference spectroscopy was used to assign 'H and =C NMR spectra of dinuclear fulvalene complexes with tungsten and molybdenum. It was found that metal-metal bonded complexes show ' H chemical shifts which are the inverse of those in non-metal-metal bonded complexes
