Abstract

Vanadium oxide (VO) is believed to play an important role in driving temperature inversion in the atmospheres of hot-Jupiters. It also characterises the spectra of late M and early L dwarfs and subdwarfs, where it is understood to be a significant opacity source. A MARVEL (measured active rotational-vibrational energy levels) analysis of the spectra of VO is performed, involving thirteen electronic states (6 quartets and 7 doublets). $^{51}$V$^{16}$O data from 14 sources are used to form three networks: hyperfine-resolved quartets, hyperfine-unresolved quartets and hyperfine-unresolved doublets. A single quartet network is formed by deperturbing the hyperfine lines and 191 lines are assigned to an intercombination 2~$^{2}\Pi$--X~$^{4}\Sigma^{-}$ band system in the visible region previously recorded by Hopkins et al. (2009), allowing the doublet and quartet networks to be merged. As a result 6535/4393 and 8610/4641 validated transitions/final energies were obtained from analysis of the hyperfine-resolved/unresolved networks. $T_0$ energy values are determined for the 2~$^{2}\Pi_{1/2}$, $\nub{}=0,1$ and 2~$^{2}\Pi_{3/2}$, $\nub{}=0$ states.
