The shapes of two hypothetical conformers of uranium trioxide UO3 were analyzed by DFT calculations and the structures of localized molecular orbitals (LMOs). It was shown that differences between the Y- and T-shapes of UO3 were due mainly to the different contributions of the U 6pz- and 6px-orbitals to the corresponding LMOs and to the formation of specifi cally shaped regions of higher electron density in the vicinity of this atom.
