%X Molecular wave-packet dynamics in oxygen are studied in the time domain, using a single-color VUVpump–VUV-probe scheme. 17-fs VUV pulses, centered at 161 nm are generated via high-order harmonicgeneration driven by an intense 800-nm pulse leading to VUV pulse energies that reach 1.1 μJ per pulse. Anall-reflective interferometric pump-probe scheme is used for studying the delay dependence of the molecularoxygen ion signal with simultaneous nonresonant photoionization of krypton as a precise timing-reference.Access to the excited dissociative state lifetime is provided by the resulting delay-dependent O<sub>2</sub><sup>+</sup> signal,ultimately limited by the molecular ionization window. The ability to use a two-photon VUV probe providesthe delay-dependent detection of O<sup>+</sup> as an additional observable, extending the dissociation observationwindow.
