The ISO SWS spectrometer has enabled us to detect for the first time the emission lines from the pure rotational transitions of molecular hydrogens (H2). We have been investigating the physical conditions and the excitation mechanisms of H2 in bright IR galaxies. Here, we present the preliminary results for NGC 6240, which is probably the most interesting object in our sample because of its largest known H2 luminosity.
