## 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

Abstract
Two conflicting assignments have been proposed for the ^13^C NMR signals of 3β²,5β²βcyclic nucleotides. This communication describes selective decoupling experiments for several cyclic nucleotides which provide the correct assignment based on unambiguous experimental evidence.

## Abstract An individual assignment of certain peaks in the proton and ^13^C NMR spectra of bilirubin and of bilirubin dimethyl ester is described. The assignment was achieved through the spectra of vinylneoxanthobilirubinic acid and by offβresonance decoupled ^13^C spectra of bilirubin dimethyl e
## Abstract Carbonβ13 chemical shifts of three arylmethyl carbanions have been determined by changing solvents and counter ions. The charge distributions in the carbanions are discussed and compared with those obtained from the ^1^H chemical shifts.
