|Abstract:||We report on the electronic and triplet state ODMR spectroscopy of s-tetrazine, 3,6-dimethyl-, 3,6-dimethoxy- and 3,6-bis(methylthio)-s-tetrazines. Zero field splitting parameters were obtained by ODMR monitoring both the delayed fluorescence and the phosphorescence in neat single crystals. The S1 and T1 exciton electronic origins are reported. The zero field splitting tensor is nearly axially symmetric with |D| approximately 0.4 cm-1. This value is found to be in good agreement with calculations based on magnetic dipole-dipole coupling in a 3B3u (nπ*) state. The calculations predict a positive value for D with the major axis passing through the C atoms at the 3 and 6 positions.|
