14 N‐ and 1 H‐Coupling constants, determined by ESR, ENDOR, and general‐TRIPLE‐resonance spectroscopy, are reported for the radical cations of tetrazinodi(heteroarenes) 1–8 . The results comply with the expectation that donor properties of these compounds are mainly due to the electron‐rich dihydrotetrazine ring.
