  We present first results from an HST WFPC2 imaging and STIS spectroscopy
program to investigate the structural and star forming properties in the
nuclear regions of the Toomre Sequence of merging galaxies. Here we discuss
V-band, I-band and H-alpha images of the nuclei. We comment briefly on the
connection between the nuclear morphology of the ionized gas and the merger
stage.
