    "abstract": "We present a systematic understanding of the rotational structure of a\nlong-range (vibrationally highly-excited) diatomic molecule. For example, we\nshow that depending on a quantum defect, the least-bound vibrational state of a\ndiatomic molecule with $-C_n/r^n$ ($n\u003e2$) asymptotic interaction can have only\n1, 2, and up to a maximum of $n-2$ rotational states. A classification scheme\nof diatomic molecules is proposed, in which each class has a distinctive\nrotational structure and corresponds to different atom-atom scattering\nproperties above the dissociation limit.",
