Full NMR spectral characteristic of eight phosphoric amides is presented. The results show that the geminal coupling constants are strongly influenced by the atom located between the coupled nuclei. Spin–spin interactions 2 J ( 31 P, 13 C) seem to be transmitted in investigated rings mainly by the two‐bond pathway, and only to a small degree via three‐bond mechanism. © 1998 John Wiley & Sons, Ltd.
