Abstract: Geometry and electronic structure of uranyl cations have been calculated with harmonicvibration analysis, using relativistic effective core pseudopotential (RECP) method. The calculated bond lengthes and vibrational frequencies have compared favorably with experimental value.U5f-O2p bond dominates in the U-O bonding, while there are strong bonds between U6p,U6d, U7s and d-s hybridizing orbitals with O2s atomic orbital. The calculated results with different spin multiplicity show that the ground state of UO22+ prefer 1∑g+.
