## Abstract An examination of published ^31^P NMR spectral data for aliphatic phosphorus compounds has revealed that chain lengthening and branching effects on the chemical shift can be interpreted in terms similar to those used for ^13^C and ^15^N shifts. For six families of phosphorus compounds,

## Abstract ^13^C and ^31^P NMR chemical shifts and coupling constants are reported and assigned for the two cyclohexylphenylphosphines, tricyclohexylphosphine and triphenylphosphine. The ^13^C NMR spectra of all compounds except dicyclohexylphenylphosphine could be assigned on the basis of APT exp
## Abstract Proton and phosphorus magnetic resonance spectra of substituted methylphosphonic acids have been determined as a function of pH. A method has been developed for measuring the ^31^P shift indirectly by optimal heteronuclear decoupling of the ^1^H spectra of samples and standards. Control
13C and 31P NMR chemical shifts and '3C-31P couplings are reported for a series of thirteen l-diethylphosphono-lhydroxycycloalkanes and their alkyl derivatives with carbocyclic ring sizes varying from four to twelve.
## Abstract The higher order highβresolution ^31^P and ^19^F NMR spectra of hexafluorocyclotriphosphazene (F~2~PN)~3~ were measured at 183 K and interpreted using subspectral analysis and iterative fitting computation. (F~2~PN)~3~ forms a rigid nineβspin system [A[X]~2~]~3~ with __D__~3__h__~ symme
