Scientific paper

Sources from a flux density limited sample drawn from the IRAS survey were selected in an attempt to determine whether emission from excited H2 is a ubiquitous property of interacting galaxies. Despite their high far-infrared luminosities, none of the galaxies in the sample show H2 emission at a level comparable to that seen from NGC 6240. The S(1) line was detected in the sample as a whole with a fractional luminosity of the order 0.00001, comparable to values seen in other interacting galaxies.
