## 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

β¦ Synopsis
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.

Replacement of H by Br leads in the Li derivatives (2)-(4) (AShd=70-90) to a four-to five-fold greater downfield shift than that in the H compounds (AS,, = 14-24). Thus it may be concluded that considerable we
The 13 C, 31 P and 1 H NMR spectra of a series of dioxaphosphinopyridines and pyridoazaphosphinines were studied. The interpretation of the chemical shifts of these compounds was based on model compounds and on selective irradiation and two-dimensional shift correlated NMR techniques.

## Abstract A comparative study of the ^13^C spectra of 13 1βpyrazolines is reported. The results show that the chemical shifts of some carbons are very sensitive to the relative positions of substituents on the 3,4 and 4,5 bonds.
## Abstract ^1^H and ^13^C NMR spectra of symmetrically substituted cyclotriphosphazenes exhibit secondβorder 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 ide
