The photoelectron-imaging spectroscopic study and chemical bonding analysis of VO₂ ^-, NbO₂ ^- and TaO₂.

ABSTRACT: The transition-metal di-oxides, namely VO₂ ^-, NbO₂ ^- and TaO₂ ^- have been studied using photoelectron velocity map imaging (PE-VMI) in combination with theoretical calculations. The adiabatic electron affinities of VO₂ ^-, NbO₂ ^- and TaO₂ ^- are confirmed to be 2.029(8), 1.901(10) and 2.415(8) eV, respectively. By combining Franck-Condon (FC) simulation with theoretical calculations, the vibrational feature related to Nb-O and Ta-O stretching modes for the ground state has been unveiled. The photoelectron angular distribution (PAD) for VO₂ ^-, NbO₂ ^- and TaO₂ ^- is correlated to the photo-detachment
