Using SEST, the Parkes antenna and the Australia Telescope Compact Array,
we have made a survey of the
12CO()
and
emission of an optically-selected sample
of ≈ 60 southern interacting and merging galaxies.
In this paper we present the data and determine global masses
of neutral gas (in molecular and atomic form) for the observed galaxies.
We have detected
in 26 systems and found that these galaxies have
less than 15% of their gas in molecular form.
Key words: galaxies: interaction / galaxies: ISM / galaxies / evolution / radio lines: galaxies
