A similar 18-cm OH absorption was found in both components of the radio source W 49. Two absorption features at the velocities of +60 and +40 km/s are attributed to the Sagittarius arm while the third absorption feature at about +15 km/s was found to be local to the source, suggesting the existence of a molecular cloud around the thermal component W 49 A. The nonthermal source W 49 B is located at the edge of the cloud about 100 pc away from W 49 A. The molecular cloud is identified with a hydrogen cloud in 21-cm studies and has the usual abundances of OH and H/sub 2/O molecules. (auth)
