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.
