## Abstract ^13^C chemical shifts and ^13^Cβ^31^P coupling constants are reported for nineteen pyrazoles bearing an Nο£ΎPPh~3~ substituent at position 5. The three heterocyclic carbons are coupled with the phosphorus (^2^__J__, ^3^__J__ and ^4^__J__). These couplings are very sensitive to the nature
## Abstract On the basis of the data obtained from ^13^C NMR spectra of 8,2β²βSβcycloadenosine 3β²,5β²βcyclic phosphate and other nucleoside 3β²,5β²βcyclic phosphate analogues, it is suggested that the published assignments of the Cβ3β² and Cβ4β² signals in nucleoside 3β²,5β²βcyclic phosphates should be rev
