HI absorption towards the central 200 pc of the Galaxy was observed with the Very Large Array (VLA) in the DnC and CnB configurations in a five pointing mosaic. The HI data has 15" angular resolution, 2.5 km s-1 velocity resolution, velocity coverage of +/- 150 km/s, and is sensitive to extended structure up to 15' in size. The overall goals of this study are to clarify the nature of the physical associations among the unique radio continuum sources of the Galactic Center (GC) and the atomic, ionized and molecular components, to determine the relative distances of these components along the line of sight, and to estimate the column densities. Here, we present such detailed studies of the interstellar components of the Sagittarius B and Galactic Center Radio Arc regions.
