✦ Synopsis
Magnetic properties and energies of linear and planar hydrogen clusters in their singlet and triplet electronic states were computed with the B3LYP hybrid density functional theory method. The energy of cyclization and change of magnetic properties in the course of cyclization of isoelectronic hydrogen clusters were used as criteria for aromaticity of these hydrogen clusters. Although only -electrons were involved, it was demonstrated that stability, as well as the change of magnetic properties in the singlet electronic state follow Huckel's rule, while in their triplet electronic state ẗhey follow Mobius' aromatic rule.
