Abstract: We present preliminary results from our ongoing single-dish and interferometric molecular gas survey toward a sample of optically selected merger remnants. We show structural and kinematical evidence that a significant fraction of merger remnants form rotating molecular disks around their central remnants, and that the size of the resultant disks in some of the galaxies are larger compared to the central bulge size inferred from the Sersic radius. The high occurrence of disks in merger remnants may support the evolutionary scenario where major mergers can evolve into a variety of Hubble types.
