Mirabel, I. F. Abstract The 21-cm wavelength neutral hydrogen spectra for 12 galaxies with strong nuclear radio sources have yielded absorption features in six of the galaxies with total velocity widths of up to 525 km/sec in N2623 and 743 km/sec in I4553. The velocity gradients and total column densities of the absorption suggest an origin in clouds located in central parts of the galaxies. H I emission having a total velocity width of 820 km/sec, measured in the isolated spiral N5635, is found to imply a mass of 1.7 trillion solar masses.
