    "abstract": "We report on the state-selective detection of near-dissociation ultracold KRb\nmolecules in the ground $X^1\\Sigma^+$ state and the metastable $a^3\\Sigma^+$\nstate. The molecules are produced by photoassociation of ultracold atoms\nfollowed by radiative decay into high vibrational levels of the $X$ and $a$\nstates. Detection utilizes resonance-enhanced one-color two-photon ionization,\nfollowed by time-of-flight mass spectroscopy. Scanning the detection laser\nfrequency over the range 582-625 nm, we observe transitions from the\n$v\u0027\u0027$=86-92 levels of the $X$ state, which are bound by up to 30 cm$^{-1}$, and\nthe $v\u0027\u0027$=17-23 levels of the $a$ state, which are also bound by up to 30\ncm$^{-1}$. The measured vibrational spacings are in excellent agreement with\nthose previously measured and those calculated from the relevant potential\ncurves. Relative vibrational populations are also consistent with Franck-Condon\nfactors for decay from the photoassociated levels.",
