We report on an orbital and temperature dependent study of the onset of coherent quasiparticles in VO single crystal. By using polarized infrared spectroscopy we demonstrate that the electronic coherence temperature is strongly orbital dependent, being about 400 K for [Formula: see text] orbitals and 500 K for the [Formula: see text]. This suggests that VO low energy electrodynamics can be described in terms of two electron liquids differently renormalized by electronic correlations.
