摘要：

The low-temperature two-photon absorption spectrum of a single crystal of CsUO2(NO3)3 is reported. The spectrum is much simpler than the single-photon absorption; together they locate nine excited electronic states. The symmetry of these states is determined, and their accurate location enables an assignment of excited-state vibrational frequencies. Only the frequencies of the uranyl cation modes are significantly modified compared to the ground state. With this data set we have refined our model of the excited-state configurations and the perturbation of the equatorial field. The results confirm that the electronic structural model of the uranyl core is transferable, with only minor modifications, between the tetragonal field of four chloride ions in Cs2UO2Cl4 and the trigonal field of the three nitrate ions in CsUO2(NO3)3.
