N2 - Synopsis We report the molecular-frame electron scattering cross sections of the 2σg → 1πg excitation in O2 and N2, obtained using an electron-ion coincidence technique. The vector correlation between the scattered electron and the fragment ion has been measured at incident electron energy of 1.4 keV. The results exhibit clear molecularorientation dependence reflecting the nodal structure of the 1πg orbital. It strongly suggests that the electron-ion coincidence technique can provide a powerful tool to investigate spatial shapes of unoccupied molecular orbitals.
