The PFI-ZEKE spectrum of Be₂O⁺ ion was recorded to obtain accurate ionization energy for Be₂O and vibrational frequency data for Be₂O⁺. A short progression of the bending mode was observed, which included bands involving odd changes in the vibrational quanta. This observation indicates that the ion and/or the intermediate state used in the excitation process deviate from D_h symmetry.
