“…However, the LFT has been successfully used to interpret the complex laser spectra and to predict the orders and energies of the low-lying states of the lanthanide-containing molecules including lanthanide monoxides [7,10,57,63]. Comparing the natural charge populations of the anions with those of the corresponding neutrals, the photodetached electron mainly comes from the nearly double occupied 6s orbital of the metal.…”

“…It should be noted that the CeO, PrO, and NdO are in the Hund's case (c) coupling limit and are characterized by the projection of the electronic angular momentum along the internuclear axis Ω and the total angular momentum J [56]. The ligand field theory (LFT) [57]. The separation of the ground state and the first excited state is very small and the two states differ only in the orientation of the angular momenta of the 4f electron core and the 6s electron, indicating that the coexistence of the transition to the first excited state X 2 3 (J a =3, Ω=3) of CeO can not be ruled in our spectrum.…”

The photoelectron imagings of LaO − , CeO − , PrO − , and NdO − at 1064 nm are reported. The well resolved photoelectron spectra allow the electron affinities to be determined as 0.99(1) eV for LaO, 1.00(1) eV for CeO, 1.00(1) eV for PrO, and 1.01(1) eV for NdO, respectively. Density functional calculations and natural atomic orbital analyses show that the 4f electrons tend to be localized and suffer little from the charge states of the molecules. The photodetached electron mainly originates from the 6s orbital of the metals. The ligand field theory with the δ=2 assumption is still an effective method to analyze the ground states of the neutral and anionic lanthanide monoxides.

“…[61,62] Many observations have since been performed. [7,[63][64][65] Linton et al [64] gave an almost complete table of spectra in the range 0-3.546 eV. Kaledin et al [65] investigated the spectra in the same range, using ligand field theory (LFT) as refined by Field.…”

Kaledin et al [65] investigated the spectra in the same range, using ligand field theory (LFT) as refined by Field. [6] Apart from LFT, which includes semi-empirical parameters, only a single theoretical calculation [10] has considered the CeO electronic excited states, looking at the lowest 16 states.…”
