Using SEST, the Parkes antenna and the Australia Telescope Compact Array, we have made a survey of the 12CO(1-0) and tex2html_wrap_inline1482 emission of an optically-selected sample of tex2html_wrap_inline1484 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 tex2html_wrap_inline1482 in 26 systems and found that these galaxies have less than 15% of their gas in molecular form.
