## Abstract The ^13^C and ^31^P NMR spectra of the triply ^13^C labelled tribenzoylphosphine [] oriented in a nematic phase have been recorded. From the spectral analysis one obtains the average CPC valence bond angle value (95.9ยฐยฑ 0.2), and the phosphorus chemical shift anisotropy ฮฯ(ฯ~โฅ๏ธ~ โ ฯ ~โฅ~
A novel nuclear magnetic resonance (NMR) experiment for facilitating the resolution and assignment of liquid crystalline 13 C NMR spectra is described. The method involves the motor-driven reorientation of the liquid crystalline director, in synchrony with the acquisition of a 2D chemical shift corr
