The dye molecule in a saturated hydrocarbon solvent (instead of the vacuum) is taken as reference state: the a-electrons of solute and solvent are treated as a continuous medium of dielectric constant E o = 2. The n-electrons of the solute are assumed to be immersed in this medium. Solvent shifts O:
## Abstract The NMR spectra of pyridine, pyrazine and imidazole are examined in acetoneβ__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.
