    "abstract": "We show how to prepare a single molecular ion in a specific internal quantum\nstate in a situation where the molecule is trapped and sympathetically cooled\nby an atomic ion and where its internal degrees of freedom are initially in\nthermal equilibrium with the surroundings. The scheme is based on conditional\ncreation of correlation between the internal state of the molecule and the\ntranslational state of the collective motion of the two ions, followed by a\nprojection measurement of this collective mode by atomic ion shelving\ntechniques. State preparation in a large number of internal states is possible.",
