AB  - The quasiparticle spectra in the metallic rutile and insulating monoclinic phases Of VO2 are shown to be dominated by local Coulomb interactions. In the rutile phase the small orbital polarization among V 3d t(2g) states leads to weak static but strong dynamical correlations. In the monoclinic phase the large 3d orbital polarization caused by the V-V Peierls distortion gives rise to strong static correlations which are shown to be the primary cause of the insulating behavior.
