## Abstract The NMR spectra of pyridine, pyrazine and imidazole are examined in acetone‐__d__~6~. The differential shifts of the ring protons are accounted for in terms of an interaction between the lone pair on the ring nitrogen atom and the carbonyl group of acetone.
## Abstract The study of a set of 3‐benzylidene‐4‐chromanones, 3‐benzyl‐4‐chromanones, 3‐benzyl‐3‐hydroxy‐4‐chromanones and 3‐benzylchromones (homoisoflavonoids) by ^13^C NMR spectroscopy shows the influence of the structure of these molecules on the chemical shifts of the more characteristic carbo
