Scientific paper

The 1665- and 1667-MHz OH absorption lines near radio source Sgr B2 are observed with the RATAN-600 radio telescope. Physical parameters are determined for five OH clouds observed at positive radial velocities, and only one of the clouds is found to have any connection with the Sgr B2 source. Results show that the observed absorbing clouds are distributed highly irregularly, and the one cloud associated with the source should belong to the extended molecular envelope with parameters confirming the rotation of the envelope.
