Abstract 17 O NMR spectroscopy of liquid acetone, oriented in a strong applied electric field, was used to measure one of the principal components of the 17 O quadrupole coupling tensor (qct). The component along the carbonyl bond was found to be (±)3.0±0.2 MHz. By comparison with other data in the literature concerning acetone and related molecules, it can be concluded that this value refers to the smallest of the principal components. The proposed NMR method is a powerful technique for obtaining information about qcts in normal liquids.
