Additivity scheme in nmr chemical shifts of disubstituted pyridines
An additivity relationship for chemical shifts similar to that found in the literature for coupling constants has been tested in eleven disubstituted pyridines. The chemical shifts of these disubstituted pyridines were measured in different solvents at different concentrations and extrapolated to in...
