This paper shows that the galactic rotation curve is determined up to galactocentric distances of 16 kpc from the relation between the parameters of the absorption lines for molecular OH clouds and the distance to them. Results are given separately for the two galactocentric guadrants which border each along the line from the center of the Galaxy to the Sun. The rotation curve so obtained repeats the kinematical laws established from observed parameters of the hydroxyl absorption lines in order to determine the distances to the molecular clouds in the Galaxy. The distance of the Sun from the center of the Galaxy is estimated.
