In this work we present a procedure for the reconstruction of the Highest Occupied Molecular Orbital in carbon dioxide by exploiting the generation of high order harmonics in a sample of impulsively aligned molecules. The procedure allows to extract the single molecule contribution to the harmonic spectrum in both amplitude and phase as a function of angular orientation and photon energy and to exploit this information in the reconstruction of the orbital. The role of multielectron contributions and of the Coulomb field of the ion on the reconstruction are discussed.

Abstract
In this work we present a procedure for the reconstruction of the Highest Occupied Molecular Orbital in carbon dioxide by exploiting the generation of high order harmonics in a sample of impulsively aligned molecules. The procedure allows to extract the single molecule contribution to the harmonic spectrum in both amplitude and phase as a function of angular orientation and photon energy and to exploit this information in the reconstruction of the orbital. The role of multielectron contributions and of the Coulomb field of the ion on the reconstruction are discussed.File in questo prodotto:
