We have analyzed proton-coupled 13C NMR and PMR spectra of pyridazine, pyrimidine, pyrazine, 1,3,5-triazine, and 1,2,4-triazine for one-molar solutions of the compounds in DMSO-D6. Comparison of the values obtained for the 13C-1H and 1H-1H spin-spin coupling constants with the values calculated on the basis of the spin-spin coupling constants in pyridine and benzene has shown that it is possible to predict the constants using linear additive equations. Substantial nonlinear deviations (5-6 Hz) are observed for 1JCH when the carbon atom is located between two adjacent nitrogen atoms. © 1986 Plenum Publishing Corporation.
