Abstrakt: Vanadium tetraoxide (VO4) has several isomers, and VO2(η²-O2) is the most stable one. The low-lying doublet states of VO2(η²-O2) and low-lying singlet states of VO2(η²-O2) were studied using the SACCI theory. The electron detachment energies from the ground electronic state of VO2(η²-O2) to the low-lying doublet states of VO2(η²-O2) were obtained. These electron detachment energies can be compared with the previous experimental photoelectron spectrum of VO4, and possible candidate states for the unassigned bands were found. The ground electronic states of VO2(η²-O2)/VO2(η²-O2) and seven doublet excited states of VO2(η²-O2) were optimised. The vertical excitation spectra of VO2(η²-O2) and VO2(η²-O2) were calculated. The lowest doublet/quartet states of VO4 and lowest singlet/triplet states of VO4 were also computed at the BP86/aug-cc-pVTZ level. [ABSTRACT FROM AUTHOR]
