Mid-infrared molecular hydrogen (H2) emission is a powerful cooling agent in galaxy mergers and in radio galaxies; （ rotational transition）[1]
Table 1. H2 Rotational Transitionsa

correlates with galaxies' molecular gas mass, with a mean absolute deviation of 0.2 dex and without evident systematics:

the [C II]-to-H2 conversion factor (alpha_[C II] ~ 30 Msun/Lsun) is largely independent of galaxies' depletion time, metallicity, and redshift.
