文摘
The R(4.5) and P(6.5) branch features of the XX (0, 0) band of praseodymium monoxide (PrO) have been studied at a resolution of approximately 50 MHz field free and in the presence of static electric and magnetic fields. The permanent electric dipole moments, μel, of 3.01(6) D and 4.72(5) D for the X2 (Ω = 4.5) and [18.1] (Ω = 5.5) states, respectively, were determined from the analysis of the Stark spectra. The magnetic ge-factors of 4.48(8) and 5.73(6) for the X2 (Ω = 4.5) and [18.1] (Ω = 5.5) states, respectively, were determined from the analysis of the Zeeman spectra. The ge-factors are compared with those computed using wave functions predicted from ligand field theory and ab initio calculations. The μel value for the X2 (Ω = 4.5) state is compared to ab initio and density functional predicted values and with the experimental values of other lanthanide monoxides.
