Comparison of the abundances of the vanadium-bearing species currently present in GGchem as a function of temperature. The dashed lines correspond to the data from previous studies already implemented in GGchem and the full lines correspond to the abundances obtained after implementing the ∆_fG values obtained for VO and VO₂ from our DFT calculations. The calculations were run at P = 1 bar and with solar elemental abundances from Asplund et al. (2009).
