Tetrazine‐based organic species are interesting intermediates for organic synthesis and represent a source of new materials bearing specific properties with potential applications in biology and material science. 1 H, 13 C, 15 N NMR measurements carried out in solution and in the solid‐state have been used to characterize a series of 3,6‐disubstituted 1,2,4,5‐tetrazine/dihydrotetrazine new derivatives. Experimental results presented here provide data for the assignment of 15 N chemical shifts including new organic small molecules; two polymers having the tetrazine ring in the main chain and several previously published compounds. We report apparently for the first time 15 N experimental chemical shift data for tetrazine systems in the solid state. Copyright © 2007 John Wiley & Sons, Ltd.
