An analysis of the rotational vibrations of water molecules is made using the model of a two-frequency pendulum in the region of a change in the type of its oscillations. Peculiarities of the phase diagrams, trajectories and velocities of the pendulum during the transition from independent two-frequency oscillations to ellipse-like oscillations analogous to the rotations of water molecules around the bond axes in the inhomogeneous field of intermolecular interaction forces are revealed
