The chemical shifts of the ring ¹H of 6-quinoxalines have been corrected from nitrogen anisotropy, nitrogen electric field and ring current effects. The corrected shifts have also been correlated with the substituent constants σ_π, and those corresponding to the π-electron charge density-ρ-distirubutions were estimated, and converted to ρ values.
