✦ Synopsis
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 (95.9°± 0.2), and the phosphorus chemical shift anisotropy Δσ(σ~∥︁~ – σ ~⊥~) which is equal to 75 ± 15 ppm.
