Ab initio calculations using the 4-31G basis set and extensive configuration interaction are reported for the 1Ag state of trans-diimide (1), the 3A″ and 1A1 states of 1,1-dihydrodiazine (2), and the ground states of the positive ions of these systems and of cis-diimide. In all cases the geometries have been optimized. The relative stabilities of these systems are discussed, with particular reference to the heat of formation of trans-1 and to the ionization potentials of 1 and 2.
