Determination of the deuterium quadrupole coupling constant in phosphine-d3 from studies in a nematic solvent

Abstract
The phosphorus and deuterium Fourier transform NMR spectra of PD3 in a nematic solvent are reported. The experimentally determined value of the deuterium quadrupole coupling constant is 7.8±0.6 kHz in good agreement with the recent theoretical predictions of Rothenberg, Young, and Schaefer. The ordering parameter is unambiguously determined from the P–D splittings, thus enhancing the accuracy of the present results over previous measurements of this kind.
