The results of a survey of H I in radio-loud and interacting galaxies are presented. This survey combines radio data taken with the Arecibo telescope and supplementary optical spectroscopic data obtained at Kitt Peak. The authors have detected four cases of H I absorption lines and report five cases of H I emission. Their analysis of a sample of 24 galaxies with H I absorption, including six classified as ellipticals or lenticulars, has uncovered a number of systematic properties. Column densities of the absorbing gas generally exceed those expected for a "Milky Way" H I disk by more than an order of magnitude. "Turbulent" noncircular gas motions of ≥102 km s-1 are evidently present, and a component of either net infall or outflow can be present as well. The set of galaxies in which H I absorption has been detected is dominated (≡70%) by morphologically peculiar objects with the eight normal galaxies in the sample having much narrower absorption lines on average. The H I properties inferred from the absorption lines are strikingly similar to those of the H I in the inner kpc of our own Galaxy.
