Electronic Structures and Photodetachment of TeO₂^-, TeO₃^-, and HTeO₄^- Anions: A Cryogenic Photoelectron Spectroscopic Study.

ABSTRACT: Cryogenic anion photoelectron spectroscopy combined with quantum chemical calculations was employed to investigate the electronic structures and photodetachment properties of TeO₂^-, TeO₃^-, and HTeO₄^- anions. The adiabatic/vertical detachment energies (ADEs/VDEs) of these anions were determined through the photoelectron spectra at 193 nm, yielding values of 2.13/1.94, 4.20/3.64, and 5.64/5.20 eV, respectively. These results align well with the theoretical calculations and were further validated through Franck-Condon factor (FCF) simulations. TeO₂^- and TeO₃^- exhibit a notable multi-reference character, with TeO₃^- showing a pronounced structural change upon detac
