## 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 off‐resonance decoupled ^13^C spectra of bilirubin dimethyl e
## Abstract The ^13^C NMR spectrum (at natural abundance) of monomeric chlorophyll α in acetone‐__d__~6~ has been recorded to re‐examine the assignments of the low field (aromatic‐olefinic) region of the spectrum. The assignments, made by the examination of the fully coupled spectrum and by the use
