Allenes, substituted with radicalic groups (CH 2⋅ , NH 2⋅+ , HN–O ⋅ ) at the terminal carbon atoms, have been investigated theoretically by ab initio methods. It is shown that the 1,3-dimethyleneallene and the 1,3-diaminoallene dication are molecules with triplet ground states due to the formation of carbene-like triplet state structures. In contrast, the closed-shell...
