Photoelectron spectroscopy of the molecular anions, Li_3O ~- and Na_3O~-

摘要

The molecular anions, Li_3O~- and Na_3O ~- were produced by laser vaporization and studied via anion photoelectron spectroscopy. Li_3O~- and Na_3O ~- are the negative ions of the super-alkali neutral molecules, Li_3O and Na_3O. A two-photon process involving the photodetachment of electrons from the Li_3O~- and Na _3O~- anions and the photoionization of electrons from the resulting Li_3O and Na_3O neutral states was observed. The assignment of the Li_3O~- photoelectron spectrum was based on computational results provided by Zein and Ortiz J. Chem. Phys. 135, 164307 (2011)10.1063/1.3636082.
