1 H and 13 C NMR spectra of symmetrically substituted cyclotriphosphazenes exhibit second‐order effects. The influence of the 31 P, 31 P coupling constants between ring phosphorus atoms on these effects was studied. Some values of this coupling constant between phosphorus bearing identical substituents were measured using 13 C satellites of the 31 P signals or by introduction of a chiral substituent on the third phosphorus atom.
