VLA Observations of the Hydroxyl Absorption Schmelz, J. T. ; Baan, W. A. ; Haschick, A. D. Abstract The VLA-A has been used to observe the hydroxyl absorption against the nuclear continuum region of NGC 3628, an edge-on spiral galaxy in the Leo Triplet. The stronger 1667 MHz component is resolved into eight spatial and velocity features. The weaker 1667 MHz transition is seen in all of these, but three are between 3 and 5 sigma. A rotating molecular disk with a radius of about 168 pc is consistent with the observations and strongly supports the disk interpretation of the H I features presented elsewhere by the authors. Several additional features at lower velocities form a second structure which is expanding away from this disk. A tidal interaction between NGC 3627 and NGC 3628 probably caused the H I extensions called the plume and the bridge and possibly caused the nuclear radio source to turn on.
