We are carrying out a program of 0.6"-0.8" resolution 12CO observations with unprecedented high sensitivity in a sample of nearby AGN and mergers with the IRAM interferometer. These data provide the exciting possibility of studying the circumnuclear regions on scales ranging from tens to a few hundred pc. For the nearby Seyfert galaxies we find that central molecular condensations observed previously at lower resolution are resolved into 100-200 pc diameter clumpy rings or disks with evidence for gas lying closer to the nucleus. We will preset results of detailed kinematic modeling of the Seyfert galaxies N1068 and N3227. For the mergers and ultraluminous galaxies, the molecular gas distributions and kinematics are providing valuable diagnostics to determine the phase of the merger. In NGC6240 the CO emission is concentrated in a rotating, but highly turbulent thick disk structure centered between the two radio nuclei. We show, from kinematic modeling of the molecular gas and from a comparison with stellar dynamics and mass distributions, that this galaxy is in an earlier merging stage than the prototypical ULIRG, Arp220, and that it may well be about to experience a major starburst like that observed in many other ULIRGS.
