Description
We study the structure and kinematics of the OH-streamer and the +80km/s cloud and their interactions with the circumnuclear disk (CND) and with other molecular clouds in the vicinity of the Galactic centre (GC), and we map OH absorption at about 6" resolution at R<=10pc from the GC, with about 9km/s of velocity resolution. The VLA was used to map OH line absorption at the 1665 and 1667MHz lambda doublet main lines of the ^2^{PI}_3/2_ state towards the Sagittarius A complex.
