    "abstract": "When molecules interact with intense light sources of femtosecond or shorter\nduration the rotational degrees of freedom are frozen during the response to\nthe strong nonperturbative interaction. We show how the frozen degrees of\nfreedom affect the measurable signals in high-harmonic generation and above\nthreshold ionization. High-harmonic generation exhibits optical coherence in\nthe signal from different orientations of the molecule. For ionization, the\ncontributions from different orientations are added incoherently. The effects\nare demonstrated for realistic alignment and orientation schemes.",
