  text: The detection of electron motion and electronic wave-packet dynamics is one
    of the core goals of attosecond science. Recently, choosing the nitric oxide molecule
    as an example, we have introduced and demonstrated an experimental approach to
    measure coupled valence electronic and rotational wave packets using high-order-harmonic-generation
    (HHG) spectroscopy [Kraus et al., Phys. Rev. Lett. 111, 243005 (2013)]. A short
    outline of the theory to describe the combination of the pump and HHG probe process
    was published together with an extensive discussion of experimental results [Baykusheva
    et al., Faraday Discuss. 171, 113 (2014)]. The comparison of theory and experiment
    showed good agreement on a quantitative level. Here, we present the theory in
    detail, which is based on a generalized density-matrix approach that describes
    the pump process and the subsequent probing of the wave packets by a semiclassical
    quantitative rescattering approach. An in-depth analysis of the different Raman
    scattering contributions to the creation of the coupled rotational and electronic
    spin-orbit wave packets is made. We present results for parallel and perpendicular
    linear polarizations of the pump and probe laser pulses. Furthermore, an analysis
    of the combined rotational-electronic density matrix in terms of irreducible components
    is presented that facilitates interpretation of the results.
