Images of the nuclear region of NGC 6240 taken in the 2.122 micron, v = 1-0 S(1) quadrupole line of molecular hydrogen demonstrate that the line emission is extended and distinct from the two nuclei producing most of the continuum emission. A region about 2 arcsec southwest of the southern nucleus produces almost 20 percent of the total line radiation, yet has no detectable 2 micron continuum. The H2 lines are asymmetric, with very little emission on the short-wavelength side of the line peaks. These results indicate that a global phenomenon, such as the dissipative collision of two disks of molecular material, is taking place.
