"Within this thesis, molecular dynamics of diatomic molecules is studied using the XUV–IR pump–probe technique. Here, a single extreme ultraviolet (XUV) photon created by high-harmonic generation ionizes the diatomic target molecule. The initiated dynamics is probed after a variable time delay by an ultrashort (12 fs) infrared (IR) laser pulse. The 3-dimensional momenta of all charged fragments are measured using a reaction microscope.\r\nIn an experiment on O_2, a nuclear wave-packet oscillation is observed on the binding potential-energy curve (PEC) of the O_2^+(a ^4Π_u) electronic state. By comparing\r\nsimulated results with experimental data, theoretically predicted PECs are tested. The experimental results are best reproduced if the wave packet is propagated on a\r\nMorse potential adjusted to the experimental data. This demonstrates the sensitivity of our method and its ability to predict accurate PECs from the measured wave-packet\r\nevolution.\r\nIn an N2 experiment, the pump–probe delay dependent yield of stable N_2^+ is observed. It is interpreted as a sequential double ionization via a highly excited antibonding cationic state. The dissociation of the intermediate state is temporally resolved and can be interrupted by multi-photon ionization with the IR pulse within ≈ 15 fs after XUV ionization."^^ . "2015" . . . . . . .
