Abstract: We report on an orbital and temperature dependent study of the onset of coherent quasiparticles in V <subscript>2</subscript> O <subscript>3</subscript> 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 V <subscript>2</subscript> O <subscript>3</subscript> low energy electrodynamics can be described in terms of two electron liquids differently renormalized by electronic correlations.
