Abstract:
    We present the results of a wide 7mm spectral survey of molecular
    absorption lines arising in the disk of a z=0.89 spiral galaxy located
    in front of the quasar PKS 1830-211. The survey was done with the
    Australia Telescope Compact Array and covers the frequency interval
    30-50GHz, corresponding to the rest-frame frequency interval 57-94GHz.
    A total of 28 different species, plus 8 isotopic variants, were
    detected toward the South-West absorption, located at about 2kpc from
    the center of the z=0.89 galaxy, which makes it the extragalactic
    object with the largest number of detected molecular species so far.

Description:
    Observations were carried out with the Australian Telescope Compact
    Array (ATCA) in two runs, a first one on 2009 September 1st and 2nd,
    and a second on 2010 March 17th.
