The 1-0 S(1) line of molecular hydrogen has been detected in the most distant "ultraluminous" interacting IRAS galaxy 14348-1447. The H2 is believed to be excited by shock waves, in analogy to other interacting and merging galaxies that have been studied in more detail. A bright Paα line was also detected, possibly indicating that a burst of star formation resulting from the interaction is well advanced.
