摘要：

We present low temperature visible and near-IR intra-5f(2) electronic absorption spectra of U(O-2,6-t-Bu(2)C(6)H(3))(4), a compound of near-T-d point group symmetry about the uranium. The ground state is tentatively assigned as having E symmetry in T-d, because the number of symmetry-allowed transitions is close to the number which we observed. Transitions out of an excited state 90 cm(-1) above the ground state were also observed. This state is assigned to A(1) symmetry, again based on counting transitions. These assignments are consistent with magnetic susceptibility measurements.
