| Abstract | Measures at the 21-cm line of neutral hydrogen are reported for a large sample of individual galaxies in groups as well as for interacting multiple-component systems. The observations of single galaxies were designed to study differential redshifts within groups. Observations of interacting systems were undertaken to obtain system redshifts as well as 21-cm profile morphology. The data, which will be used in future analyses, are presented here along with a discussion of interaction morphology from the 21-cm profile point of view. Together the profile samples encompass the full range of dynamical states in which the gas components of galaxies are observed, from relaxed to violently disrupted. |
