    "abstract": "A simple and non-destructive method for identification of a single molecular\nion sympathetically cooled by a single laser cooled atomic ion in a linear Paul\ntrap is demonstrated. The technique is based on a precise determination of the\nmolecular ion mass through a measurement of the eigenfrequency of a common\nmotional mode of the two ions. The demonstrated mass resolution is sufficiently\nhigh that a particular molecular ion species can be distinguished from other\nequally charged atomic or molecular ions having the same total number of\nnucleons.",
