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'.
