| Zusammenfassung: | Copyright (c) 2008 John Wiley & Sons, Ltd. Heteronuclear Overhauser effect spectroscopy (HOESY) is a powerful method for tracking geometrical proximities between two heteronuclei (for instance, (1)H and (13)C, as this will be the case here). The method is based on cross-relaxation arising from dipolar interactions. Sensitivity permitting, it is applied in the 2D mode yielding all spatial correlations in a single experiment. Whenever sensitivity is not sufficient, it can be applied in the one-dimensional mode by selectively inverting one particular proton. In that case, it yields, from the carbon-13 spectrum, remote spatial correlations. The method has been employed here for the discrimination between two possible E or Z isomers in a medium-size molecule |
