## Abstract ^13^C NMR chemical shifts and ^13^C^31^P couplings are reported for triphenyl phosphate and 13 alkyl derivatives. In __ortho__‐alkylated materials, it is found that the upfield γ shielding effect is only operative when the carbon atom, situated γ to the exocyclic oxygen, bears at least

## Abstract Natural abundance ^13^C NMR studies have been carried out on a series of organophosphorus compounds possessing PN bonds. For the first time a __one__‐__bond__ temperature‐dependent ^13^C—^31^P nuclear spin coupling was observed for the __P__‐phenyl carbons in bis(__N__,__N__‐dibenzylam
## Abstract Natural abundance ^13^C NMR studies have been carried out on a series of phospholes and dibenzophospholes. The systems were analyzed with respect to ring conformation and substituent orientation. Assignments of all chemical shifts have been made by investigating partially relaxed invers
