A sensitive nuclear double reson,~.nce method enables measurement of naturally abundant 170 nuclear quadrupole resonance t\_ransition frequencies in powdered o~anic compounds. The nuclear quadrupole parameters enable the identification of resonances from C=O, C-O-H, and C-O-C groups in a set of comp
## Abstract The ^17^O nuclear quadrupole resonance (NQR) frequencies have been measured in phenylphosphinic acid and phenylphosphonic acid using nuclear quadrupole double resonance. The quadrupole coupling constants have been determined with an uncertainty of Β± 10 kHz and the asymmetry parameter Ξ·
Temperature dependence of 17 O nuclear quadrupole resonance frequencies was measured in solid 2-nitrobenzoic acid by a 1 H-17 O nuclear quadrupole double resonance technique. The experimental results show the presence of a fast exchange of hydrogen atoms between two nonequivalent positions within th
