Synopsis An ultrashort XUV laser pulse ionizes the D2 molecule creating an electronic and nuclear wave packet, with the dominant contributions from the 2sσg and 2pπu ionic states. A delayed interaction with a 780 nm IR field ejects the second electron, leading to the Coulomb explosion of the molecule, whose nuclear fragments, recorded in coincidence, map the dynamics associated to those two ionic excited states. By varying the orientation of the light polarization, one can control the molecular
