Correlation of deuterium quadrupolar couplings and carbon-13 chemical shifts in ordered media by multiple-quantum NMR
We report a simple and robust NMR approach capable of correlating deuterium quadrupolar splittings with carbon-13 chemical shifts in oriented materials. The technique, which is based on heteronuclear multiple-quantum spectroscopy, results in two-dimensional maps that are very useful for the assignment of deuterium NMR spectra. The experiment has been employed to measure and assign all quadrupolar couplings produced by a perdeuterated liquid crystal.
