英文摘要: We report a combined photoelectron velocity-map imaging spectroscopy and density functional theory investigation on lutetium monoxide anion. Transition between the X-1 Sigma(+) anion electronic ground state and the neutral X-2 Sigma(+) electronic ground state is observed. Vibrationally resolved spectra were obtained at four different photon energies, providing a wealth of spectroscopic information for the electronic ground states of the anionic lutetium monoxide and corresponding neutral species. Franck-Condon simulations of the ground-state transition are performed to assign vibrational structure in the spectra and to assist in identifying the observed spectral bands. The electronic ground state of LuO- is found to have a vibrational frequency of 743 +/- 10 cm(-1) and an equilibrium bond length of 1.841 angstrom. The electron affinity of LuO is measured to be 1.624 +/- 0.002 eV. The fundamental frequency of ground-state LuO is estimated to be 839 +/- 10 cm(-1). (C) 2014 AIP Publishing LLC.
