High-resolution (Theta = 4 arcseconds .4 x 3 arcseconds .1) CO observations of the IR luminous system VV 114 (IC 1623) using the Owens Valley Millimeter array reveal 5.1 x 1010 Solar masses of H2 in a 5.9 x 3.1 kpc (15 arcseconds x 8 arcseconds) bar with two 4-6 kpc long tails (D = 80 Mpc for H 0= 75). The wide separation (6 kpc) of the merging optical galaxies, the extended gas distribution, and the noncircular gas kinematics suggest that VV 114 is in an early stage of a gas-rich merger. The concentration of gas and its dominance …
