Abstract
The E.S.R. spectra of the anions of 2,5- and 2,6-dimethylpyrazine have been investigated and analysed. Satisfactory agreement between experimental and calculated hyperfine splittings is found if a single Q value is used to relate the spin density and the hyperfine splitting for nitrogen. In a simple MO calculation both the inductive and heteroatom models give better agreement than the hyperconjugative model.Keywords
