[HTML][HTML] Excited states of lutetium oxide and its singly charged cation

Vibronic spectra of lutetium oxide (LuO) seeded in supersonic molecule beams are
investigated with mass-analyzed threshold ionization (MATI) spectroscopy and second-
order multiconfigurational quasi-degenerate perturbation (MCQDPT2) theory. Six states of
LuO and four states of LuO+ are located by the MCQDPT2 calculations, and an a 3 Π
(LuO+)← C 2 Σ+(LuΟ) transition is observed by the MATI measurement. The vibronic spectra
show abnormal vibrational intervals for both the neural and cation excited states, and the …
