  bibo_abstract:
  - Alkali dimers, Ak2, located on the surface of a helium nanodroplet, are set into
    rotation through the polarizability interaction with a nonresonant 1-ps-long laser
    pulse. The time-dependent degree of alignment is recorded using femtosecond-probe-pulse-induced
    Coulomb explosion into a pair of Ak+ fragment ions. The results, obtained for
    Na2, K2, and Rb2 in both the ground state 11Σ+g and the lowest-lying triplet state
    13Σ+u, exhibit distinct, periodic revivals with a gradually decreasing amplitude.
    The dynamics differ from that expected for dimers had they behaved as free rotors.
    Numerically, we solve the time-dependent rotational Schrödinger equation, including
    an effective mean-field potential to describe the interaction between the dimer
    and the droplet. The experimental and simulated alignment dynamics agree well
    and their comparison enables us to determine the effective rotational constants
    of the alkali dimers with the exception of Rb2(13Σ+u) that only exhibits a prompt
    alignment peak but no subsequent revivals. For Na2(13Σ+u), K2(11Σ+g), K2(13Σ+u)
    and Rb2(11Σ+g), the alignment dynamics are well-described by a 2D rotor model.
    We ascribe this to a significant confinement of the internuclear axis of these
    dimers, induced by the orientation-dependent droplet-dimer interaction, to the
    tangential plane of their residence point on the droplet.@eng
