## Abstract Solvent effects on the nitrogen NMR shieldings of indolizine and three azaindolizines are presented for a range of thirteen solvents. The results are discussed in terms of hydrogenโbonding an solvent polarity effects. โPyridineโtypeโ nitrogen atoms show a much larger range of solvent ef
## Abstract The NMR spectra of pyridine, pyrazine and imidazole are examined in acetoneโ__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.
