Description:
    A 330-360 GHz spectral survey of the hot molecular core associated
    with the `cometary' ultracompact H II region G 34.3+0.15 observed with
    the James Clerk Maxwell Telescope has detected 338 spectral lines from
    at least 35 distinct chemical species. 70 lines remain unidentified.
    Chemical abundance and rotation temperature have been determined by
    rotation diagram analysis for 13 species, and lower limits to
    abundance found for 38 others. The spectral lines identified are
    tabulated in Table 1 in the form of observed frequency, line
    brightness temperature and width, the observing session in which the
    line was observed, the species, transition and its theoretical
    frequency (if a positive identification can be made). Any comments are
    listed in the final column.

Note (1): The bracket indicates that the value listed is not likely to be
           accurate, most probably due to self-absorption and/or emission in
           the off-source reference beam
Note (2): The code indicates whether the line was detected in the first (1)
           or second (2) observing session, in the main (m) or image (i) band.
Note (3): * - If the identification of the species and transition is ambiguous,
               the various alternatives are given, with the favoured
               identification shown with an asterisk.
          ? - Question marks denote uncertain detections
          b - Blended lines are marked by `b'.
